A book is pushed up a ramp by a force. Calculate the net work done by :
a. Fpush
b. Fgrav
c. Fnormal
Let fnet = 5 Newtons and displacement of the object be 5 m up the ramp,
so the net work done by Fpush = 5 * 5 = 25 J. is the Work net by grav = mgsin@ * 5? and net work by Fnormal = mgcos@ * 0.5? is the work of gravity negative and Fnormal positive? Kindly guide me to the correct answers. Thanks
