A 0.22kg billiard ball traveling at a speed of 16m/s strikes the side rail of a pool table at an angle of 60?.
If the ball rebounds at the same speed and angle, what is the magnitude of the the change in its momentum?
A uniform plank of length 5.70 m and weight 215 N rests horizontally on two supports, with 1.1 m of the plank hanging over the right support. To what distance x can a person who weighs 452 N walk on the overhanging part of the plank before it just be..
This parallel group is connected in series with a 22.0 Ω resistor. The total combination is connected across a 18.0 V battery. Compute the current delivered to the 130 Ω resistor.
suppose the radius of the ball is very small compared to other length scales in the problem. Take starting level as step 0, the next step down as step 1, and so on.
