Question

A body of mass 50 gms is allowed to fall freely under gravity.calculate its momentum after 5 seconds (g=980 cm power minss 2

​

Answer 1

2.45 kg m /s or 245000 g cm / sec.

.

Explanation.

.p = m v

.m = 50 g or 0.05kg

Firstly finding velocity.

V = u + gt

Here u = 0 ( as in case of free fall)

V = 9.8 x 5

V = 49m/s

Now,...

P = 0.05 x 49

P = 2.45 kg m / s.

Done dude .

I have solved it in SI unit you can convert it according to the system you want your ans.

Ok bye
