Question #296143

Suppose that the net external force

(push minus friction) exerted on a

lawnmower is 51 N (about 11 lb)

parallel to the ground. The mass of

the mower is 24 kg. What is its

acceleration?

Expert's answer

Given:

$F=51\rm \: N$

$m=24\rm \: kg$

The Newton's second law says

a=\frac{F}{m}=\rm\frac{51\: N}{24\: kg}=2.1\:\rm m/s^2
