Mass of block = 4 kg

Angle of inclination = 30°

Force needed to move the block at constant velocity = mg × Sin 30°

Force required = 4 × 9.8 × 0.5

Force required = 19.6 N

Power = Force × velocity

Plugging the values:

Power = 19.6 × 3

Power = 58.8 Watts

Hence, the power delivered by the force to move the block at the constant speed up the inclined plane is 58.8 Watts.

Answer 2

Answer:

Power = 60 watt .............
