Question

Momentum of an object is 28kg ms-1

. If its velocity is 1.4 m/s. What would be

the mass of the object ?

(a) 20g (b) 2 x 104 g (c) 0.2 x 104

g (d) 0.2 x 106

g​

Answer 1

Answer:

20kg

Explanation:

Let the mass be m

Now,

m*v=p(v=velocity and p=momentum)

m*1.4=28

m=28/1.4kg

m=20kg
