A block of mass m = 3.5 kg, moving on a frictionless surface with a speed Vmo = 6.2 m/s makes a sudden perfectly elastic collision with a second block of mass M, as shown in the figure. The second block is originally at rest (VMO = 0). Just after the collision, the 3.5-kg block recoils (moves left) with a speed of Vm1 = 1.5 m/s and the unknown mass block moves right with a speed of VM1 = 2.1 m/s. What is the mass M of the second block? m M m M before after

As shown in the figure (Figure 1), a superball with mass m equal to 50 grams is dropped from a height of hi=1.5m . It collides with a table, then bounces up to a height of hf=1.0m . The duration of the collision (the time during which the superball is in contact with the table) is tc=15ms . In this problem, take the positive y direction to be upward, and use g=9.8m/s2 for the magnitude of the acceleration due to gravity. Neglect air resistance.

Find the y component of the momentum of the ball immediately after the collision, that is, just as it is leaving the table. Find JyJyJ_y, the y component of the impulse imparted to the ball during the collision. Find the y component of the time-averaged force Favg,yFavg,y, in newtons, that the table exerts on the ball. Find Kafter−KbeforeKafter−Kbefore, the change in the kinetic energy of the ball during the collision, in joules.
