Asked by Breanna

A force of 20 N is needed to overcome a frictional force if 5 N and accelerate a 3 kg mass across a floor. What is the acceleration of the mass?
Answered by Damon
F = m a
F = 20-5 = 15N
so
15 = 3 a
a = 5 m/s^2
Answered by james
a= 5m/^2

Given :
Mass ,m=3 Kg and Frictional Force, f = 5N Force ,f = 20N

Thus accuration of the mass, a = F-f/m
=20-5/3 =5m/s^2
