Question

11. A body of mass 500 g, initially at rest, is acted upon
by a force which causes it to move a distance of 4-
m in 2 s, Calculate the force applied.
​

Answer 1

Answer:

finding a first by

2nd law of motion

s=ut+1/2at^2

s=4m

t=2s

a=?

u=0

4=0+2*1/2*a2^2

4=2a

a=2m/s

for force

F=ma

m=500g into kg =0.5

a=2m/s

F=0.5*2

F=1N
