Homework Statement
A skier of mass 70.0kg is pulled up a slope by a motor-drawn cable. How much work is required to pull the skier 60.0m up a 35 degree slope (assume to be frictionless) at a constant speed of 2.0m/s?
Mass = 70.0kg
Distance = 60.0m
Angle = 35
Velocity/Speed = 2.0m/s
Homework Equations
I would typically use the formula "W = (F)(D)(Cos0)...(cos0 = cos angle)
I can't do this because I don't have the force. I have looked through all my notes, ask other people who take physics at my school and attempted to search online but I am unable to figure anything out.
My Question is, how do i find force when given mass, distance, angle, and velocity/speed.
The Attempt at a Solution
Well i have looked for about 1 hour and 30 mins and I was unable to find anything. If someone could explain to me how to find force it would be greatly appreciated.
Thank you
