Formula of Force =》 $\frac{Work}{Time}$


But here the values of Work and time are not given. So, we will use the another method of Power


Power = Force × Velocity


P = 200N × 16m/s

P = 3200 W

OR

3200 J/s

Answer 2

Answer:

• 3200 W

Explanation:

Given

• Force = 200 N
• Velocity = 16 m/s

To find

• Power

Solution

⟶ Power = force × velocity

• 200 × 16
• 3200 N.m/s
• 3200 W

Hence, the power spent by the man is 3200 W.
