A 9 kg asteroid is traveling through space at 2.5 m/s toward a spaceship. To avoid a collision, an astronaut, with the help of a backpack rocket, exerts a force of 25N on the asteroid in the opposite direction for 4 seconds. a) Find the asteroid s final speed. m/s (Hint: Assume the initial speed f the asteroid is in the positive x direction.) b) How long should she have pushed in order to just stop the asteroid? Time to stop asteroid = seconds

In 1898, the world land speed record was set by Gaston Chasseloup-Laubat driving a car named Jeantaud. His speed was 39.24 mph (62.78 km/h), much lower than the limit on our interstate highways today. Repeat the calculations of Example 2.7 (acceleration for first 6 miles, time of timed mile, acceleration for last 6 miles) for the Jeantaud car. Compare the results of the ThrustSSC to Jeantaud.
You are in charge of improving the safety of a carnival ride. The ride involves a 165 kg cart travelling at 13.1 the wall. m S toward a brick wall. The cart is supposed to stop at the last second just before it hits You want the cart to come to a complete stop within a time of 1.85 s. What force is required to stop the cart in this amount of time? F = N Based on the parts you have been provided, you are able to exert a force of 3820 N on the cart. What is the maximum initial speed that the cart could have and still stop within 1.85? Vmaximum = m S
Which of the following situations would result in a greatest impact force: a. the crash is head-on between two identical cars both moving at 30mph and b. the crash is head-on into a stationary brick wall with a velocity at 30mph? Explain why.
1. A proton of mass 1.67 x 10-27 kg is initially at rest. It then moves through 1.80 cm along a straight line, reaching a speed of 3.00 x 106 m/s.

The height of a ball is thrown straight up sith a certain force is a function of the time (t) from which it is released given by f(t)=-0.5gt2+40t (where g is a constant determined by gravity). a. How does the value of t at which the height of the ball is at a maximum depend on the parameter g? b. Use your answer to part (a) to describe how maximum height changes as the parameter g changes. c. Use the envelope theorem to answer pare (b) directly. d. On the Earth g=32, but this value varies somewhat around the globe. If two locations had gravitational constants that differed by 0.1, what would be the difference in the maximum height of a ball tossed in the two places?
An airplane slows to a stop as it moves along the runway. Its mass is 3.50 x 105 kg, its speed is 75.0 m/s at the instant the plane lands on the runway and the force to slow the airplane is 7.25 x 105 N. a) What is its speed 10.0 seconds after the plane lands on the runway? b) How far has it traveled in this time?
A student pushes a 12-kg block on a frictionless, horizontal surface. If the block is initially at rest, what is the speed of the block after the student pushes the block for 5 seconds with an acceleration of 2.0 m/s/s? O 2.0 m/s 6.0 m/s 10 m/s 60 m/s
A student launches a small rocket which starts from rest at ground level. At a height of h = 1.8 km the rocket reaches a speed of vf = 342 m/s. At that height the rocket runs out of fuel, so there is no longer any thrust propelling it. Take the positive direction to be upward in this problem B: After the rocket's engine turns off at a height of h = 1.8 km, it continues to move upward due to the velocity that it reached. What is the rocket's acceleration, in meters per second squared, during the period from engine shutoff until it returns to the ground? Ignore air resistance. C: Calculate the maximum height, in meters above ground level, that the rocket reaches.
Starting at time t=0t=0, net force F1F1 is applied to an object that is initially at rest. If the force remains constant with magnitude F1F1 while the object moves a distance dd, the final speed of the object is v1v1. What is the final speed v2v2 (in terms of v1v1) if the net force is F2=2F1F2=2F1 and the object moves the same distance dd while the force is being applied? (the answer in the box is incorrect, and 2 is also incorrect)
A 25g ball slides down a smooth inclined plane 0.850 m high that makes an angle of 35 degrees with the horizontal. The ball slides down into an open box of 150 g mass. The ball and the box slide off the end of a table 1.0 m high. a.) How far from the base of the table will the box and ball hit the ground? b.) What is their final velocity?
1.a. A ball has an initial speed of 5 m/s, going to the right then hits a wall. After hitting the wall, the ball now goes to the left with a speed of 2 m/s. What is the magnitude of the force exerted by the wall to the ball if the time of contact between the two is 0.02 s? Hint: Be careful with the direction of the velocities. 1.b. A boxer punches a 60-kg bag, with the speed of fist at 8 m/s. After the punch, the bag flies away and the hand comes to a complete stop. What is the rebound velocity and kinetic energy of the bag? Assume that the moving part of the hand weighs 5 kg.
