Question

A force 10N is applied on a mass of 5kg which is rest . then find the kinwtic​

Answer 1

Force on the body= 10N= Mass(acceleration)

10= 5(acceleration)

acceleration= 2m/sec²

I can't solve this question without time...

for how much duration of time is the force applied?..... waiting......

(*assuming the force is applied for 5sec ...

acceleration= change in velocity/time=2

change in velocity/5=2

change in velocity=10m/s

final-initial velocity=10

final-0=10

final velocity=10+0=10m/s

K.E.= 1/2(mass)(velocity)²=1/2(5)(10)²

=250 J*)
