A 43 gg ball is fired horizontally with an initial speed v0 toward a 100 g ball that is hanging motionless from a 1.0-m long string. The balls undergo a head-on, perfectly elastic collision, after which the 100 g ball swings out to a maximum angle θmax = 52 ∘. What was v0? Express your answer with the appropriate units.

Situation 7. A ball of mass 0.220 kg that is moving with a speed of collides head-on and elastically with another ball initially at rest. Immediately after the collision, the incoming ball bounces backward with a speed of 3.8m/s.    C. Supposed that a ball is dropped from a height of 2.60 m. If the coefficient of restitution between the ball and the ground is 0.60, to what height will it bounce?

I.  A lump of clay (m = 3.01 kg) is thrown towards a wall at speed v = 3.15 m/s.  The lump sticks to the wall.  (a) What kind of collision is it?  Is momentum conserved during this collision?  Why or why not?

Two shuffleboard disks of equal mass, one orange and the other green, are involved in a perfectly elastic glancing collision. The green disk is initially at rest and is struck by the orange disk moving initially to the right at Voi = 7.40 m/s as in Figure a, shown below. After the collision, the orange disk moves in a direction that makes an angle of 0 = 40.0° with the horizontal axis while the green disk makes an angle of ø = 50.0° with this axis as in Figure b. Determine the speed of each disk after the collision. Vof = m/s V gf m/s After the collision of Before the collision a た。

A steel ball of mass 0.610 kg is fastened to a cord that is 35.0 cm long and fixed at the far end. The ball is then released when the cord is horizontal, as shown in the figure. At the bottom of its path, the ball strikes a 2.60 kg steel block initially at rest on a frictionless surface. The collision is elastic. Find (a) the speed of the ball and (b) the speed of the block, both just after the collision. (a) Number (b) Number -1.623 100 Unit Unit m/s m/s

This amazing summer adventure is finally winding down with some pool. Unfortunately, this pool table is wonky and some of the balls are larger than the others! Anthony hits the cue ball (mass = 0.15 kg) and it moves at 5 m/s when it strikes head on into the number 3 ball (mass = 0.30 kg). After this inelastic collision, the cue ball moves off at 60 degrees relative to the +x axis and the number 3 ball moves off at -30 degrees relative to the +axis as shown. What were the speeds of the two balls after the collision?

Two gliders with mA = 0.50 kg, mB = 0.40 kg, collide elastically on a frictionless surface. Glider A with a spring bumper initially moves to the right with the speed of 3.0 m/s and glider B with a spring bumper initially moves to the left with the speed of 6.0 m/s. What is the final velocity of the glider A after collision?
