What will be the change of velocity of a 50kg object if a force of 2,000N is applied to it for 0.010 seconds?

0.4m/s

Explanation:

where F= force, m= mass, and a=acceleration

we also know that,

a = Δv / t where Δv = change in velocity and t = time

thus F = m ( Δv / t)

0.4m/s = Δv

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7
