Answer to Question #338067 in Mechanics | Relativity for MCK

Question

A Ricocheting Bullet.

0.100-kg stone rests on a frictionless, horizontal surface. A bullet of mass 6.00 g, traveling

horizontally at 350 m/s, strikes the stone and rebounds horizontally at right angles to its original direction with a speed of 250

m/s.

(a)

Compute the magnitude and direction of the velocity of the stone after it is struck.

(b)

Is the collision perfectly elastic?

Answer 1

a)

$v_1=100~\frac ms .$

b)

$v_2=50~\frac ms.$
