A car of mass 800kg moves from rest on a horizontal track and travels 60m in 20s with uniform acceleration. Assuming there were no frictional forces, calculate the accelerating force

A. 240.0N
B. 800.0N
C. 1600.00N
D. 2400.0N

Correct Answer: Option A

A. 240.0N

Explanation

S = at + ½at²

60 = 0 x 20 + ½ x a x 20

a = 310m/s²

F = ma = 800 x 310=240N
