A book is pushed up a ramp by a force. Calculate the net work done by :(adsbygoogle = window.adsbygoogle || []).push({});

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
