... 16. A steel ball whose mass is 2.0 kg is rolling at a rate of 2.8 m/s. What is its momentum? p = mv = (2.0 kg)(2.8 m/s) = 5.6 kg*m/s 17. A race car leaves the starting line and travels 36000 m in the first 600 seconds of the race. They are then forced to take a pit stop and don’t go anywhere for 250 ...

... ball at the elephant with a speed of 7.81 m/s. When the ball bounces back toward you, what is its speed? Our simplest formulas for speed after an elastic collision relied on one body being initially at rest. So lets try a frame where one body (the ball) is at rest! What is the speed of the elephant ...

... Two blocks of masses 20 kg and 5 kg respectively are connected by a light inextensible string, P. A second light inextensible string Q, attached to the 5 kg block, runs over a light frictionless pulley. A constant horizontal force of 250 N pulls the second string as shown in the diagram below. The m ...

... The impulse on a body is defined as its change in momentum. Impulse = change in momentum = mv – mu where u is the initial velocity and v is the final velocity. Impulse is denoted by the vector I. Note that the impulse I that a body A exerts on a body B is equal to the magnitude of the impulse that B ...
