Hi Im having trouble finding the correct method for tackling this question. Should I be using equations of motion?because then I know that gravity would make it accelerate at 9.81m/s^2 but Im confused... any help would be appreciated.(adsbygoogle = window.adsbygoogle || []).push({});

A toy truck of mass 80g is released from heighthand rolls down a slope as shown. What would the heighthhave to be for the truck to reach a speed of 4.0m/s at the bottom of the slope, assuming friction is negligible.
