Question

A bullet of mass 20 g moving with a speed of 500 m/s strikes a wooden block of mass 1 kg and gets embedded in it. Find the speed with which block moves along with the bullet.

Answer 1

m1 = 20g = 0.020kg

v1 = 500m/s

m2 = 1kg

v2 = ?

m1v1 = m2v2

0.02 × 500 = (1 + 0.02) v2

10 = 1.02v2

10 / 1.02 = v2

v2 = 9.80m/s
