Question

10) A body of mass 50 kg is allowed to fall freely under gravity. calculate its momentum
after 15 sec [g 9.8 m/s?)​

Answer 1

Explanation:

Mass of the body = 50kg

Time = 15 sec

Momentum = ?

According to Newton's 1st law

V = U + gt

V = 9.8*15 ( Initial vel is zero )

Velocity = 147 m/s

We know that product of mass and velocity gives us momentum.

M = mv

M = 50*147

M = 7350 is the required answer
