Answer:
3 m/s
Explanation:
Parameters given:
Mass of first bowling pin, m = 1.7 kg
Initial velocity of first bowling pin, u = 3.8 m/s
Final velocity of first bowling pin, v = 0.8 m/s
Mass of second bowling pin, M = 1.7 kg
Initial velocity of second bowling pin, U = 0 m/s
Let the final velocity of the second bowling pin be V
Using the principle of conservation of momentum:
Total initial momentum = Total final momentum
m*u + M*U = m*v + M*V
(1.7 * 3.8) + 0 = (1.7 * 0.8) + (1.7 * V)
6.46 = 1.36 + 1.7V
1.7V = 5.1
V = 5.1/1.7 = 3 m/s
