The free-fall acceleration is g = 9.81 m/s*. Pleasc answer the following questions ©theexpertta.com 14% Part (a) Write an expression for the magnitude of the force of gravity on the block, Pg, in terms of the given quantities and variables available in the palctte 14% Part (b) Calculate the magnitude of the force of gravity on the block, F, in Newtons 14% Part (c) In what direction does the force of gravity act? 14% Part (d) Write an expression for the magnitude of the total force of the system in the y-direction, FT in terms of the forces of the system Grade Summary Deductions Potential 16% 84% Submissions Attempts remaining: 6 aT % per attempt)Explanation / Answer
The total force on the block can be given by
FT = maT + mg - FN
where FN is the normal force acting in the positive y-direction
