Question

If a loaded truck that can accelerate at 1 m/s2 loses its load and has two-thirds of the original mass, what acceleration can it attain from the same driving force?

Answer 1

do you know a relation between force mass and acceleration?

Answer 2

if so, solve for a, then 2/3 the m, and keep the F constant, and you should end up with a scalar of the original setup
