Question

A 25 newton force applied on an object moves it 50 meters. The angle between the force and displacement is 40.0°. What is the value of work being done on the object

Answer 1

Work is defined by the following formula:

$$A = F * S * \cos (\alpha)$$

where: F - force

S - displacement

$\alpha$ - the angle between the force and displacement

So, substituting given values, we obtain:

$$A = 25 * 50 * \cos (40) = 1250 * \cos (40) = 957.5 \approx 958 \mathrm{~Jl}$$

Answer: 958 Jl
