A small, 250 g cart is moving at 1.60 m/s on a frictionless track when it collides with a larger, 4.00 kg cart at rest. After the collision, the small cart recoils at 0.860 m/s. What is the speed of the large cart after the collision?

A person with a mass of 50 kg is driving her car at a velocity of 20 m/s.  The car is involved in a small collision and the airbag is deployed.  the airbag provides a stopping force of 1200 N.  The person's final velocity is 0 m/s.  How long does it take for the person to be stopped by the airbag?

A railroad car of mass 2.85 x 10^4 kg moving at 2.60 m/s collides and couples and with two coupled railroad cars, each of the same mass as the single car and moving in the same direction at 1.20 m/s. A. what is the speed of the three coupled cars after the collision? B. how much kinetic energy is lost in the collision?

A 0.240-kg billiard ball that is moving at 3.00 m/s strikes the bumper of a pool table and bounces straight back at 2.40 m/s (80% of its original speed). The collision lasts 0.0150 s.  Calculate the loss of energy in this case. options + 70 J -59.0 J -40.0 J 0 J

Two remote control cars with masses of 1.15 kilograms and 1.98 kilograms travel toward each other at speeds of 8.41 meters per second and 3.97 meters per second, respectively. The cars collide head-on, and the less massive car recoils with a speed of 2.25 meters per second.a. What is the final speed of the second car?  b. How much kinetic energy is lost in this collision?

A hockey puck moving at 0.460 m/s collides with another puck that was at rest. The pucks have equal mass. The first puER is deflected 37.0° to the right and moves off at 0.360 m/s. What is the speed of the second puck after the collision? m/s

On a frictionless air track where motion is constricted to a line, a 2.0-kg glider moving in the positive x-direction at 4 m/s collides elastically with a 3.0-kg glider moving in the negative x-direction at 6 m/s. What are the velocities of both masses after the collision?

Cisco Webex 20210510091148742.pdf PDF b My Questions | bartleby /kerli/Downloads/20210510091148742.pdf 2. A 1.2-kg object moving with a speed of 8.0 m/s collides perpendicularly with a wall and emerges with a speed of 6.0 m/s in the opposite direction. If the object is in contact with the wall for 2.0 ms, what is the magnitude of the average force on the object by the wall1?

A 1.72 kg block of soft wood is suspended by two strings from the ceiling. The wood is free to rotatein pendulum-like fashion when a force is exerted upon it. An 8.5 g bullet is fired into the wood. Thebullet enters the wood at 431 m/s and exits the opposite side shortly thereafter. If the wood rises to aheight of 13.8 cm after the collision, then what is the exit speed of the bullet?
