Question

The diagram shows a ballistic pendulum. A 200 g bullet is fired into the suspended 4 kg block of wood and remains embedded inside it (a perfectly inelastic collision). After the impact of the bullet, the block swings up to a maximum height h. The initial speed of the bullet was 50 m/s.

Answer 1

In this case, Momentum will be 

P = mv

P = .2 x 50

\(P=\frac{0.2\times50}{10}\)

P = 10 kg m/s
