A steel ball of mass 300.0 g moving with a velocity of 2.25 m/s [E], strikes a second ball of mass 0.20 kg. initially atrest. The collision is glancing one, causing the moving ball to have a velocity of 1.75 m/s [ E30N] after the collision.Draw a detailed diagram of before and after collision. Determine the velocity (mag & direction) of the second ball.

You put an antimatter explosive in a 133 kg space rock, initially moving to the right at 34 m/s. This time, upon detonation, the rock fractures into three pieces. A 16 kg chunk is observed to zip off to the right (the positive direction) at 60 m/s. A 69 kg chunk is observed to zip off to the left at 59 m/s. Calculate the final velocity of the third chunk, in m/s. (Please answer to the fourth decimal place - i.e 14.3225)
Soru E (5 Puan) While a disk with a mass of ma=5 kg travels at VA=4 m/s speeds in the +x direction, it collides with another disk with a mass of mg=2 kg on its way.

As part of a carnival game, a ?b=0.628 kgmb=0.628 kg ball is thrown at a stack of 17.8 cm17.8 cm tall, ?o=0.363 kgmo=0.363 kg objects and hits with a perfectly horizontal velocity of ?b,i=11.3 m/s.vb,i=11.3 m/s. Suppose that the ball strikes the topmost object. Immediately after the collision, the ball has a horizontal velocity of ?b,f=3.60 m/svb,f=3.60 m/s in the same direction, the topmost object has an angular velocity of ?o=3.23 rad/sωo=3.23 rad/s about its center of mass, and all the remaining objects are undisturbed. Assume that the ball is not rotating and that the effect of the torque due to gravity during the collision is negligible. If the object's center of mass is located ?=12.5 cmr=12.5 cm below the point where the ball hits, what is the moment of inertia ?oIo of the object about its center of mass?
