Question
Two 1.5 kg balls are attached to the ends of a thin rod of negligible mass, 72.0 cm in length. The rod is free to rotate in a vertical plane about a horizontal axis through its center. With the rod initially horizontal as shown, a 0.62 kg wad of wet putty drops onto one of the balls with a speed of 3.8 m/sec and sticks to it.
1. During the collision, what is conserved? Linear Momentum,
2. What is the angular speed of the system after the putty wad hits?
3. Through what angle will the system rotate until it momentarily stops?

- If a cart of mass 350 grams moving at speed of 4.5 m/s hits an end-stop and rebounds at a speed of 3.2 m/s, what is the change in momentum, in units of kg.m/s? A cart has the rubber bumper attached to the force sensor, and it moves and collides with an end-stop. In the collision, it suffers a change in momentum = 4.05 kg.m/s, and the time during which the collision takes place is 0.182 seconds. Calculate the average force applied on the cart by the bumper, in newtons.arrow_forwardIn an Atwoods Machine lab with m1 = 0.1 and m2 = 0.13 observed acceleration is 1.20 m/s^2.
