Question

A 30kg mass is pulled across a nearly fiction less surface. The pulling force of 90N makes an angle of 35degrees with the horizontal. The mass has a velocity of 4.0m/s to the right at time t=0.0s

a) what is the upward normal force exerted by the surface on the mass?
b) what is the acceleration of the mass?
c) how far does the mass have to be pulled before its velocity reaches 12m/s(to the right)
d) how far does the mass travel from t=0.0s to t=8.0s?

Can anyone help me get started on this problem? :(
