The runway of an airport in Oman has been designed such that the
lowest acceleration for a plane to take off is 14.3 m/s?. The take-off speed
for this plane will be 54.9 m/s. Assuming this minimum acceleration, then
the minimum allowed length (m) for the runway is:
O a. 105.38
O b. 52.69
O c. 421.54
O d. 210.77
A car travels along the vector d1 = 4.6i+3.1 (m). and then travels along the vector d2 = 2,41+5.81(m). How far is
km
Car A is traveling at a constant speed va = 130
at a location where the speed
hr
limit is 100 km/hr. A police officer observes this speed via radar. At the moment Car
A passes the officer, the police car begins to accelerate at a constant rate of 6 until a
speed of 160 is achieved, and the speed is maintained. Determine the distance (ih m)
hr
required for the police officer to overtake Car A.
A ball is thrown vertically upward with an initial velocity of 10 m/s from the top of a building of height 200 m. 3 seconds later, a stone is thrown downward from the same point with an initial speed of 24 m/s
a) When and where the ball and the stone meet?
b) What are their velocities when they meet?
g=9.8m/s2

- A celebrated Mark Twain story has motivated contestants in the Calaveras County Jumping Frog Jubilee, where frog jumps as long as 2.2 m have been recorded. If a frog jumps 2.2 m and the launch angle is 45, find (a) the frogs launch speed and (b) the time the frog spends in the air. Ignore air resistance.arrow_forwardYou drop a ball from a window on an upper floor of a building and ii is caught by a friend on the ground when the ball is moving with speed vf. You now repeat the drop, but you have a friend on the street below throw another ball upward at speed vf exactly at the same time that you drop your ball from the window. The two balls are initially separated by 28.7 m. (a) At what time do they pass each other? (b) At what location do they pass each other relative the window?arrow_forwardA ball is thrown straight up. It passes a 2.00-m-high window 7.50 m off the ground on its path up and takes 0.312 s to go past the window. What was the ball's initial velocity? Hint: First consider only the distance along the window, and solve for the ball's velocity at the bottom of the window. Next, consider only the distance from the ground to the bottom of the window, and solve for the initial velocity using the velocity at the bottom of the window as the final velocity.arrow_forward
