Question

A 2.0-kg ball has a momentum of 25 kg×m/s what is the balls speed

Answer 1

Momentum = (mass) x (speed)

(25 kg-m/s) = (2.0 kg) x (speed)

Speed = (25 kg-m/s) / (2.0 kg) = 12.5 m/s

Answer 2

As we know, momentum= mass*velocity
acc. to ques. mass = 2kg
momentum= 25kg-m/s
momentum = mass*velocity (speed)
velocity (speed) = momentum/mass
velocity(speed)=25/2
=12.5m/s
