In a soccer free kick, a player kicks a stationary ball toward the goal that is 130 m away and 20 m high. The ball is hit at an angle of 350 from the horizontal, and air resistance is negligible. Calculate (a) The initial speed of the ball (b) How long does the ball take to reach the goal? (c) The velocity components and the speed of the ball when it passes over the top of the goal.

During the siege of Constantinople that led to its conquest by the Ottomans in 1453, the Hungarian engineer Orban built a set of bombards (primitive cannon) to throw enormous stones at the city to breach its walls. The largest of these could throw a 300 kg stone a distance x = 2 km. Assume that the stone was launched at an angle of 0 = 45 degrees above the horizontal; in the absence of air resistance, this gives the largest range. a) What speed did the stone have to be launched at to achieve this range? b) How long was the ball in the air? c) How fast was the ball traveling at the apex of its flight?
In a friendly game of handball, you hit the ball at ground level and send it towards the wall with a speed of 18 m/s at an angle of 40o above the horizontal. (a) If the wall is 3.8 m away how high is the ball when it hits the wall? (b) What are the x and y velocity components just before it strikes the wall? (c) What is the magnitude and direction at this time?
A cannonball is fired off a cliff at an angle of 25 degrees with respect to the horizontal. The cliff is 80 m high. The initial speed of the rock is 50 m/s. (a) What is the range of the rock? (b) When the cannonball hits the ground what is the magnitude of its total velocity?
For all questions, assume concepts such as friction or air resistance are negligible, unless stated otherwise in the question. A ball is launched from ground level at an angle of 60˚ and with a speed of 15 m/s. a)What is the maximum height the ball will reach? b)How far horizontally will the ball travel before returning to ground level?
An object is launched at a velocity of 20 m/s in a direction making an angle of 25° upward with the horizontal. (with solutions each)a) What is the maximum height reached by the object?b) What is the total flight time (between launch and touching the ground) of the object?c) What is the horizontal range (maximum x above ground) of the object?
An object is projected with initial speed v0 from the edge ofthe roof of a building that has height H. The initial velocity of the objectmakes an angle a0 with the horizontal. Neglect air resistance. If a0 is 90, so that the object is thrown straight up (but misses the roof on the way down), what is the speed v of the object just before it strikes the ground?
An object is launched at a velocity of 20 m/s in a direction making an angle of 25⁰ upward with horizontal. (A) what is the maximum height reached by the object? (B) what is the total flight time (between launch and touching the ground) of the object? (C) what is the horizontal range (maximum x above the ground) of the object? (D) what is the magnitude of the velocity of the object just before it hits the ground?
A celebrated Mark Twain story has motivated contestants in the Calaveras County Jumping Frog Jubilee, where frog Jumps as long as 2.20 m have been recorded. If a frog jumps 2.20 m and the launch angle is 57.0°, find the frog's launch speed and the time the frog spends inthe air. Ignore air resistance. (a) the frog's launch speed (in m/s) (b) the time the frog spends in the air (in s)
A diver jumps off a diving board horizontally with an initial velocity of 5m/s. He lands in the water 4m to the right of the base of the diving board. a) How high above the ground is the diving board? b) What speed will the driver have as he hits the water?
A tennis player serves the ball with an initial speed of 23.6 m/s, from a height of 2.37 m above the court. If the net is at a distance of 12 m and has a height of 0.90 m, determine what is indicated in each section: a) The angle that the throw must have so that the ball can pass over the net. b) The time it takes for the ball to hit the ground, assuming the person on the other side of the net fails to return it. c) If the other person has a height of 1.70 m, and his throw is made at 2.20 m, indicate in what position he must be in order to return the ball.
Question 5 5. A horizontal projectile is shot with an initial velocity of 15 m/s from a height of 3.46 m above the ground. Neglecting air-resistance, what is the magnitude of the final velocity (m/s)?
A student standing on a cliff throws a pebble from a vertical height of d = 8.0 m above the level ground with velocity vo = 19 m/s at an angle = 23° below the horizontal, as shown. It moves without air resistance. Use a Cartesian coordinate system with the origin at the initial position of the nebble. VO Part (a) With what speed, in meters per second, does the stone strike the ground? Part (b) If the pebble had been thrown from the clifftop with the same initial speed and the same angle, but above the horizontal, would its impact velocity be different?
