In the figure, block A (mass 1.7 kg) slides into block B (mass 2.2 kg), along a frictionless surface. The directions of velocities before and after the collision are indicated; the corresponding speeds are vAi = 5.4 m/s, VB¡ = 2.2 m/s, and VBf = 4.2 m/s. What is velocity Vaf (including sign, where positive denotes motion to the right)? Number i Units TP P VB VBI

A ball struck by a bat experiences a change in momentum of 42 kg m/s . If the time of interaction is 0.29 s, what is the magnitude of the average force acting on the ball (in N) ?

A moving cart of mass 3.5 kg crashes into a stationary cart of mass 10.5 kg as shown. The carts are prevented from touching one another during the collision by a pair of neodymium magnets mounted on the ends of the carts and positioned for repulsion. After separating, the more massive cart moves to the right at 1.4 m/s. What are the final speed and direction of motion of the less massive cart? strong magnets Vfi VGi = 0 3.5 kg 10.5 kg Frictionless surface

On a frictionless horizontal air table, puck A (with mass 0.255 kgkg ) is moving toward puck B (with mass 0.367 kgkg ), which is initially at rest. After the collision, puck A has velocity 0.121 m/sm/s to the left, and puck B has velocity 0.655 m/sm/s to the right. What was the speed vAivAiv_Ai of puck A before the collision? Calculate ΔKΔKDeltaK, the change in the total kinetic energy of the system that occurs during the collision.

(ODC-1) Consider two hockey pucks, each with mass 1.25 kg, on frictionless ice. Puck A is initially moving due east at 2.35 m/s towards puck B, which is initially stationary. The pucks. collide head on. After the collision, puck B moves east with a speed of 1.45 m/s. (a) What is puck A's speed (in m/s) after collision? What direction is it moving in? (b) How much kinetic energy (in Joules) is lost from the system during the collision? (c) If the collision were completely elastic, what wold the final speed and direction of each puck be?
