Question

A body of mass of 1 kg undergoes a change of velocity of 5 metre per second in 4 seconds what is the force acting on it

Answer 1

Answer:

i thougt it is usefull

Step-by-step explanation:

acceleration=change in velocity/time

Force=mass*acceleration

Force=1*4/4

Force=1*1

Force=1N

Answer 2

Hey Mate !!!

m = 1kg

v = 5m/s

t = 4 s

to find = F

we know that, a = v-u/t

a = change in velocity/ time

a = 5/4 m/s^2

F = ma

F = 1*5/4

F = 5/4 N = 1.25 N
