a) Constant velocity means that there is no acceleration and the net force is zero.

b/c) He is accelerating down the hill which means that there is a net force.

Draw an fbd then you can create an equation for a/b/c based on the parameters.

nah he did that with the f=ma parameters but u need to put the angel so if it is like u say it will go like this f=ma=53kg x o m/sThere are two forces, the force of the wind and his weight.

a) Constant velocity means that there is no acceleration and the net force is zero.

b/c) He is accelerating down the hill which means that there is a net force.

Draw an fbd then you can create an equation for a/b/c based on the parameters.
