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.

Question

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.

bobpursley · Answer

PE change= workin-frictionalloss workin=pullingforce*distance frictionalloss=frictionforce*distance
