Question

A 3000 kg truck starts from rest and rolls down a hill with constant acceleration. It travels a distance of 400.0 m in the first 25.0 s. Calculate the net force on the truck. Round your answer to the nearest whole number.

Answer 1

Answer is 3840N

dist. = 1/2at^2

from this equation we get acceleration

a=800/625m/s^2

now Force=Mass*acceleration

= 3000*800/625

=3840N
