Question

A boy of mass 30 kg while running at constant velocity has a momentum .of 180 Ns. The constant
velocity of the boy is :
(A) 3 ms1
(B) 6 ms *
(C) 18 ms' (D12​

Answer 1

Answer:

6 m/s

Explanation:

Given ,

mass (m) = 30 kg

momentum (p) = 180 Ns

We know,

p = m × v

=> 180 = 30 × v

=> v = 180/30

=> v = 6 m/s

Answer 2

Answer:

p=mv

180/30=6m/s
