An 80 kg skater and a 50 kg skater stand motionless on very slippery ice. They push off each other. Which skater moves faster after they stop pushing? a)  The 80 kg skater   b)  The 50 kg skater.  c)  Both have the same speed.  d)  Both will have a speed of zero.

A car is stopped for a traffic signal. when the light turns green, the car accelerates, increasing its speed from 0 to 4.90 m/s in 0.812 s. A. what is the magnitude of the linear impulse experienced by a 72.0 -kg passenger in the car during the time the car accelerates? B. what is the magnitude of the average total force experienced by a 72.0-kg passenger in the car during the time the car accelerates?

1. A large semi truck has a mass of 35,000 kg. It collides head on with a car that has a mass of 1000 kg. The car’s initial velocity is 10 m/s and the truck’s initial velocity is 5 m/s in the opposite direction. What can you say about the forces and velocities of the two vehicles? a) The force that the truck makes on the car is much larger than the force the car makes on the truck so the car’s velocity changes much more than the truck’s does. b) The force that the truck makes on the car is equal to the force the car makes on the truck so the car’s velocity changes by the same amount that the truck’s velocity does. c) The force that the truck makes on the car is equal to the force the car makes on the truck but the mass of the truck is much larger than the car so the car’s velocity changes by much more than the trucks does. d) The mass of the truck is so much larger than the car that the force of the truck on the car is much greater than the force the car puts on the truck and the car…

Just before a bouncy ball hits a wall, it is traveling parallel to the ground at 18 m/s, and it then bounces directly backwards at 17 m/s. The interaction time with the wall was 0.40 ms (4.0 x 10-4 s). If the ball's mass is 0.17 kg, what is the average magnitude of the force of the wall on the ball during their interaction? A. 7700 N B. ON C. 7200 N D. 15000 N O A B

Brad is the catcher for the Varsity baseball team. He exerts a forward force on the 0.145-kg baseball to bring it to rest from a speed of 38 m/s. During the process, his hand recoils a distance of 0.13 m. Determine the force which is applied to the baseball by Brad. a) -1.42N b) -805 N c) -142 N

37. Suppose that an object is pushed with a steady force along a frictionless surface. When you multiply the object's mass by the length of time for which it is pushed and then multiply the result by the object's acceleration over that period of time, you get Ā. momentum B. impulse C. velocity D. a meaningless quantity

What is the acceleration of a 4700 kg rocket taking off from the moon, where the acceleration of gravity is only 1.6 m/s2, if the rocket expels 8.00 kg of gas per second at an exhaust velocity of 2.20 x 103 m/s? m/s2 Additional Materials O Reading

1. Which of the following statements is/are TRUE? a. The coefficient of restitution can take up a value greater than 1. b. The center of mass can be located outside the object, especially those with curved structures. c. The initial momentum of a moving body is directly proportional to the force applied and to the duration of its application. d. The final velocities of two colliding objects can be calculated if the coefficient of restitution is given along with the objects' initial velocities.
