Question
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.
a) Find the y component of the time-averaged force Favg y, in newtons, that the table exerts on the ball.
b) Find Kafter−Kbefore, the change in the kinetic energy of the ball during the collision, in joules

- Hi there! I need some help! I am really confused. I do not know how to solve this! A block of mass m = 4.4 kg, moving on frictionless surface with a speed vi = 9.2 m/s, makes a perfectly elastic collision with a block of mass M at rest. After the collision, the 4.4 kg block recoils with a speed of vf = 2.5 m/s. Mass m is closest to: Thank you!arrow_forwardTwo cars collide at an intersection. Car A�, with a mass of 1900 kgkg , is going from west to east, while car B�, of mass 1300 kgkg , is going from north to south at 14.0 m/sm/s . As a result of this collision, the two cars become enmeshed and move as one afterwards. In your role as an expert witness, you inspect the scene and determine that, after the collision, the enmeshed cars moved at an angle of 55.0 ∘∘ south of east from the point of impact.How fast were the enmeshed cars moving just after the collision?arrow_forwardA billiard player sends the cue ball toward a group of three balls that are initially at rest and in contact with one another. After the cue ball strikes the group, the four balls scatter, each traveling in a different direction with different speeds as shown in the figure below. If each ball has the same mass, 0.16 kg, determine the total momentum of the system consisting of the four balls immediately after the collision. (Assume v1 = 0.33 m/s, ?1 = 70°, v2 = 0.49 m/s, ?2 = 30°, v3 = 0.23 m/s, v4 = 0.48 m/s.)arrow_forward
