Question

A forces 150N applied at an angle of 60 degree to the horizontal to pull a box through a distance of 5m. Calculate the work done?

Answer 1

Answer:

Step-by-step explanation:

The horizontal compnent of force is 150 cos60 = 75N

distance is = 5m

Work done =  horizontal compnet * distance

                   =75*5

                   =375 Nm

Answer 2

Answer:

375 J

Given:

Force applied = 150N,

Angle = 60° to the horizontal.

Distance = 5 m

To Find:

Work done.

Step-by-step explanation:

Force is divided into two component

• Horizontal component = Fcos60°
• vertical component = Fsin60°

Now, horizontal component will pull the box. i.e. 150cos60°

⇒ 150 × 1/2 = 75N

we know,

work done = force × distance

Therefore,

work done = 75 × 5

work done = 375 Joule

Hence, work done is 375 joule.
