A 0.12kg bullet is initially traveling 120m/s when it strikes a stationary 4.3kg block. After the collision the block (with the bullet embedded inside) swings up as shown. Neglect drag and the initial height of the bullet above the reference level. KE GPE unit unit unit bullet (time 1) block* (time 2) block* (time 3) * The bullet is embedded in the block at these times. How fast was the block traveling after the impact? m/s v How much heat was generated during the impact? To what height (h) did the block swing? unit

Ted Cmass=4Okg) and fredCmass = 60kg)are Stationary on frictionless ice, as seen in the drauing Poelow. Fredis holding a 10kg medicine ball. Fred throws it at 5mls to Ted who catches it. Ted throws the ball back to Fred at 7m/s, and Fred Catches it Ted D→Fred a) what is Ted's speed after catching the ball and throwing it back to Ered? b)What is Fred's speed after catching the ball thrown' from Ted?

A mass ma = 2kg slides down slippery ramp, reaching a speed v = 10 m/s at the bottom. After reaching the level ground ma collides with mass mg = perfectly inelastic collision. 3kg at bottom, sticking together in a a.) What was the height of the ramp, assuming that m, started from rest? b.) How fast were the combined masses ma and mg moving after sticking together? c.) The combined mass runs into a spring, which brings it to a stop after being compressed 7 cm. What is the spring constant k ?

6. A 2.0 kg bag is held by a string to the ceiling as shown in the diagram below. A 10 g bullet strikes the stationary bag. The speed of the bag and bullet after the collision is 0.80 m/s. Assuming there is no friction, determine the maximum height of the bag after the collision. Please hand write it, clearly.

A 110-kilogram tackler traveling at 2.5 m/s makes a head-on collision with and successfully carries an 88-kilogram halfback traveling at 5.0 m/s.
