Question

A car of mass 1000 kg is moving with a velocity 72 kilometre per hour .find its momentum?

Answer 1

Explanation:

we have,m=1000kg

v=72km/hr=72*5/18=20m/s

momentum,p= mv

= 1000*20

=20000kgm/s

Answer 2

Answer:

P = 2000 Ns

Explanation:

m = 1000 kg

v = 72 km / hr = 7200 / 3600 m/s = 2 m/s

P = ?

P = mv

P = 1000 x 2

P = 2000 Ns
