Question

Engine of a truck applies a force of 200 N on the truck and the truck moves with uniform velocity of 30 m/s. Work done by friction force in 1 minute time is​

Answer 1

Answer:

For an object to move with constant velocity, net external force experienced by it must be equal to ZERO i.e F

external

=0

Thus a friction of 200 N must be exerted on the cabinet so that it moves with a constant velocity under the applied horizontal force of 200 N.
