Question

A body of mass 5 kg is moving with a velocity f 10 m/s. A force is applied to it so that in 25 seconds it attained a velocity of 35 m/s. calculate the magnitude of the force applied.

Answer 1

Answer:

x do instinctive Harold

Answer 2

given

mass =5 kg

time =25 sec

u = 10m/s

v= 35 m/s

we know

f= change in momentum ÷ time

F= (mv-mu) ÷ t

F= {5(35) - 5(10)} ÷ 25

F= {5(25)} ÷ 25

F= 5 newton
