A Box (15.0 kg) is pulled up a 37 degree ramp with a force of 295 N. The frictional force acting on the block is 56.0 N. If Box travels 12.0 m up the ramp, determine the change in Box’s PEgrav.
Answered by bobpursley
PE change= workin-frictionalloss
workin=pullingforce*distance
frictionalloss=frictionforce*distance
