check_circleExpert Solution
Step 1

Given: work done = 3.7 × 103 W

Efficiency = 81%

mass of block, m = 450 kg

Coefficient of friction = 0.35

Find: Speed of the block

Step 2

To calculate speed of the block, use the relation as:

Power = Force × velocity

Step 3

Where, Power and Force can be ca...
