Homework Statement
A boy on a board B slides down a slope. The angle of the slope to the horizontal is 30°. The total resistive force F acting on B is constant.
The boy on the board B moves with velocity v down the slope. The variation with time t of v is shown in Fig. 3.2.
Calculate the resistive force.
Homework Equations
wsinA----?
The Attempt at a Solution
Resistive force= WsinA
= 75 x 9.81 x 0.5
= 367.5 N
My answer does not match with the correct answer. How do you solve this?
