A beach ball rolling in a straight line toward you at a speed of 0.5 m/sec. Its momentum is 0.25kg m/sec. What is the mass of the beach ball?
m v = .25
m (1/2) = .25
m = .5 Kg
To find the mass of the beach ball, we can use the equation:
Momentum = mass × velocity
Given that the momentum is 0.25 kg m/sec and the velocity is 0.5 m/sec, we can rearrange the equation to solve for the mass:
mass = Momentum / velocity
mass = 0.25 kg m/sec / 0.5 m/sec
mass = 0.5 kg
Therefore, the mass of the beach ball is 0.5 kg.
