A 10kg toy truck moves at 5m/s East. It collideds head-on with a 5kg toy car moving 10m/s West. What is the total momentum of the system?

23. Please give detailed answer.

V ? A hockey puck of mass 4m has been rigged to explode, as part of a practical joke. Initially the puck is at rest on a frictionless ice rink. Then it bursts into three pieces. One chunk, of mass m, slides across the ice at speed v. Another chunk, of mass 2m, slides across the ice at speed 2v, in a direction at right angles to the direction of the first piece. From this information, find the velocity of the final chunk. Initally at rest

15. A 10000Kg car is moving toward north at a speed of 3m/s at noon. One hour later, the car is moving toward east at 4m/s. The change in momentum of the car during that onehour period is (a) 10000Kgm/s, toward east. (b) 50000Kgm/s, toward 37 degrees north of east. (c) 50000Kgm/s, toward 53 degrees north of east. (d) 50000Kgm/s, toward 37 degrees south of east. (e) 50000Kgm/s, toward 53 degrees south of east.

1. a. Starting from Newton's second law of motion, prove that impulse is equal to a change in momentum. b. A particle of mass m moves with a momentum of magnitude p. Show that the kinetic energy of the particle KE = i. =p²/2m

A 100g ball traveling horizantally at 25 m/s strikes a wall and rebounds at 19 m/s. What is the magnitude of the impulse experienced by the ball during the rebound? A. 1.2 Ns B. 1.8 Ns C. 4.4 Ns D. 5.4 Ns E. 7.2 Ns

3. A 95.5-kg football player running north at 6.25 m/s is tackled by a 105-kg player running south at 4.90 m/s. If they stick together during the collision, what is the magnitude and direction of their velocity right after the collision?

4. A 1590-kilogram truck moving with a speed of 23.0 m/s runs into the rear end of a 1090-kilogram stationary car. If the collision is completely inelastic, how much kinetic energy is lost in the collision? sf6 60 ssfot sf60

1. Two balls with mass mA = 3.0kg and mg = 2.0kg are initially moving towards each other with initial velocities as vai = 1.0m/s and Vai = -4.0m/s. If the collision between them is elastic, what is the Vai final velocities of the balls? Before Collision A VA Bi m, After Collision V Af A m, V.

I. Conceptual Physics. Justify your answer. 1. A 10-gram rubber ball and a 10-gram clay ball are thrown at a wall with equal initial speeds. The rubber ball bounces, the clay ball sticks. Which ball exerts a larger impulse on the wall? Justify your answer.
