Question

Hi, I don't know if I was given enough or have too much uneccesary information to solve this problem, but here it is.

An 80 kg guy is running on a flat surface at a velocity of 10 m/s. He gets on a 4 kg skateboard that is sitting at rest at the top of a 45-degree inclined plane (see drawing). If the time taken to travel from point A to point B is 6 seconds and only gravitational acceleration is acting on the guy/skateboard unit, find

a) the velocity of the unit when t = 3 seconds;

b) the height h at point A.

I'm also not sure which part should be solved first. Thanks.
