A large plate of mass m=0.800 kg is dropped and breaks into three pieces on a frictionless ground. Using the data shown in Fig. 3.1, (a) find the magnitude and direction of the velocity of the third piece after collision. If there is no loss of energy before and after the plate breaks, (b) what is the speed of the large plate before breaking? If the plate is dropped into a cart of mass 4.20 kg moving at a speed v=3.00 m/s on a frictionless ground, as shown in Fig. 3.2, (b) what is the speed of the cart if the plate lands on the cart without breaking apart? (c) While the cart continues to move forward at the speed determined in (b), if the plate is thrown horizontally backward from the cart with a speed 5.00 m/s relative to the ground after the plate landed on the cart, as shown in Fig. 3.3, (d) what is the speed of the cart after the plate is thrown backward? While the cart continues to move forward at the speed determined in (b), if the plate is thrown backward from the cart in the direction  30 . 0 ° above the horizontal with a speed 5.00 m/s relative to the ground after the plate landed on the cart, as shown in Fig. 3.4, (e) what is the speed of the cart after the plate is thrown backward? test3_fig3.jpg

Particle A of mass 2.00 kg moves to the east with a speed 10.0 m/s and particle B of mass 1.50 kg moves to the north. They suffer a collision. After the collision, particle A moves 60.0° north of east with a speed 10.0 m/s and particle B moves 15.0° south of east. (a) What are the speeds of particle B before and after the collision? (b) What are the magnitude and direction of the impulse that particle A exerts on particle B? (c) What is the change of kinetic energy of the two-particle system before and after the collision? If particle A  moving to the east with a speed 10.0 m/s and particle B moving to the north with the speed determined in (a) stick together after the collision, (d) what are the magnitude and direction of the velocity of the particles after the collision and (e) what are the magnitude and direction of the impulse that particle B exerts on particle A?
