A0.50 kg ball traveling at 6.0 m/s due east collides head on with a 1.00 kg bai in the opposite direction at-12.0 m/s. After the collision, the 0.50 kg ball move 14.0 m/s. Find the velocity of the second ball after the collision. Show your wc + mvzi = m,vf + m;v,f*

A 600-kg car headed north and an 800-kg car headed west collide at anintersection. After the collision, the 600-kg car is skidding at a speed of 22 m/s ata direction of 25º north of west. The 800 kg car is going 34 m/s at a direction of32º west of north.a. What were the initial speeds of the cars?b. What was the change in energy of the system due to the collision?

Jill threw a dodgeball completely horizontal in x-direction with velocity of +5 m/s and mass of .5 kg. At the same time her friend threw a dodgeball with the same mass in the -x direction and a velocity of -2 m/s. The balls hit each other, and Jill's ball was deflected 30° above the original path, while her friend's deflected 20⁰. below the initial path. a. Ignoring gravity, solve the velocity of each ball after the collision, using a free body diagram. b. If both balls had a magnitude of 3 m/s, how much kinetic energy was "lost" during the collision?

A 70.0 kg ice hockey goalie, originally at rest, has a 0.280 kg hockey puck slapped at him at a velocity of 43.5 m/s. Suppose the goalie and the puck have an elastic collision, and the puck is reflected back in the direction from which it came. What would the final velocities ?goalie and ?puck of the goalie and the puck, respectively, be in this case? Assume that the collision is completely elastic.

A 10.0-g bullet moving at 323 m/s is fired into a 1.00-kg block at rest.  The bullet emerges (the bullet does not get embedded in the block) with half of its original speed.  What is the velocity of the block right after the collision?Round your answer to the nearest hundredth.

A rutber bell and a clay ball have oqual mass and are dropped onto a digital scale. The rubber ball bounces back to nearly the same height. The clay bell sticks to the scale when it hits. For the (single) imeraction with the scale. a. Whar is the ratio af the change of the clay ball's momentum to the change of the rubber ball's momentum? b. What is the ratio of the impulse impaned to the clay ball to the impulse imparted so the rubber ball? Iruter c. Which of the following graphs could epresent, o the same scale, the force exerned by the scale on each ball as a function of time? Select an answer for the rubber ball and an ansaer for the clay ball. F(N) F(N) F(N) I (s) I (s) 1 (s) F(N) F(N) clay ball: rubber ball: B) 1 (s) D) I (s)
