A constant force of 900 N pushes a 100 kg mass up the inclined plane shown above at a uniform speed of 4 m/s. The power developed by the 900 N force is most nearly
400 W
800 W
900 W
1000 W
3600 W

3600 W

Explanation:

From the question given above, the following data were obtained:

Force (F) applied = 900 N

Mass (m) of object = 100 Kg

Velocity (v) = 4 m/s

Power (P) =?

Power can also be defined as the product of force and velocity. Mathematically it can be expressed as:

Power (P) = Force (F) × velocity (v)

P = F × v

With the above formula, we can obtain the power developed by the 900 N force as follow:

Force (F) applied = 900 N

Velocity (v) = 4 m/s

Power (P) =?

P = F × v

P= 900 × 4

P = 3600 W

Thus, the power developed by the 900 N is 3600 W
