Question

A ball has 2 kg*m/s of momentum when thrown with a velocity of 8 m/s outwards. Find the mass of the ball.

Answer 1

Answer:

As, we know momentum = mass × velocity that is p = mv

we have momentum (p) = 2 kg m/s

and velocity (v) = 8 m/s

so substitute values in p=mv

2 kg m/s = m × 8 m / s

m = 2 / 8 kg = 0.25 kg

Therefore, mass of substance is 0.25 kg.

2/8 in fractional form.....
