Question

A constant force acts on an object of mass 24 kg for a duration of 4 seconds .It increases the objects velocity from 22m/s to 29m/s. Find the magnitude of the applied force. (Write only numerical value without unit)​

Answer 1

Explanation:

force = mass x acceleration

acceleration is not given so we use accelration formula

therefore, force = mass x (v-u)/t

f = 24 x (29-22)/4

f = 24 x 7/4

f = 168/4

f = 42 Newtons
