Answer:
4ms^-2
Step-by-step explanation:
m = 45Kg, Frictional force = 120N, Applied force = 300N, a = ?
Firstly, you find the net force acting on the body
Net force = Applied force - Frictional force
Net force = 300N - 120N = 180N
F = 180N
using the formula for Force
F = ma
Then making acceleration subject of the formula; you will get:
a = F/m
a = 180N/45Kg
a = 4ms^-2
