Question

a force acting in the body mass 400 gram displace through 500 cm in 5 sec. find the magnitude of force if the inital velocity of body is zero

Answer 1

Explanation:

Acceleration, a = v - u/ t u = 0, v = 5/5 = 1m/s (distance converted to meters, 1m = 100cm)

a = 1/5 = 0.2m/s^2

Force = mass× acceleration = 400/1000× 0.2 = 0.08N (Mass converted to kgs 1kg = 1000g)

hope this will help you
