Asked by Philomena
A 5kg block is being moved to 3m by a force of 50N inclined to the horizontal at an angle of 30°. Assuming that a friction force of 5N opposing its motion ,find the acceleration of the block and the work done by the block.

If the movement was in the direction of the force...
workdone=change in KE + change in PE
and workdone = force*distance=50*3=150Joules
netforce=mass*acceleration
50-mg*sin30=m*A
put mass m, and g in, solve for acceleration A
