To calculate the work done, you can use the formula:

[W = F \times d \times \cos(\theta)]

Where:

(W) = Work done
(F) = Force applied (in the direction of motion)
(d) = Distance moved
(\theta) = Angle between the force and the direction of motion

In this case:

(m) = 3 kg (mass)
(g) = 9.8 m/s² (acceleration due to gravity)
(d) = 10 m (distance)
(\theta) = (\frac{\pi}{3})

[F = m \times g \times \sin(\theta)] [F = 3 \times 9.8 \times \sin\left(\frac{\pi}{3}\right)]

[W = F \times d \times \cos(\theta)] [W = (3 \times 9.8 \times \sin\left(\frac{\pi}{3}\right)) \times 10 \times \cos\left(\frac{\pi}{3}\right)]

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
