Work on a Block Siding Up a Frictionless incine trotorlessindred plane, which makes an angee.230" wth respect to up the plane al coratant speed Part A The block moves we constant speed what ste work We done on the blockby all foroesaste block moves a distance L 400 m up up an indne he indine Inckade only he work done aher the block has started moving atoonstant speed, not the work needed to startthe block moving from rest. Express your answer numerically in joules. Husta My Amateu Ghre Review Part Incorrect Try Again: 2 attempts remaining Part B

Explanation / Answer

Since we know according to work energy theorem that change in kinetic energy is equal to work done by all the forces.

Here in your questions particle is moving with constant speed which indicates the change in kinetic energy is zero.

If change in kinetic energy is zero work done by all the forces is also zero

So answer is zero
