Angular momemtum : mass * tangential speed * distance to the center = 50*2.1*3.6=37800 J.s
Because it is physically true day really know that by just knowing it very well
The resulting change in momentum of the system will be +18.6 Ns. The momentum is conserved.
<h3>What is the law of conservation of momentum?</h3>
According to the law of conservation of momentum, the momentum of the body before the collision is always equal to the momentum of the body after the collision.
The given data in the problem is;
m is the mass =6.0 kg
t is the time interval=2 second
From Newton's second law;

From the graph;

The change in the momentum is;

Hence, the resulting change in momentum of the system will be +18.6 Ns.

Period, T = 1/ f.
f = frequency = 200 Hz.
Period T = 1/200 = 0.005 seconds.
