Question

You are pulling a child in a wagon. The rope handle is inclined upward at a 60∘ angle. The tension in the handle is 20 N.

Answer 1

• Angle (θ) = 60°
• Force (F) = 20 N
• Distance (s) = 200 m
• Therefore, work done
• = Fs Cos θ
• = (20 × 200 × Cos 60°) J
• = (20 × 200 × 1/2) J
• = (20 × 100) J
• = 2000 J

Answer:

2000 J

Hope you could get an idea from here.

Answer 2

S O L U T I O N:

Here we've been provided with the information i.e

• Force (F) = 20N

• Distance (s) = 200m

• Angle (θ) = 60°

Ans we have given to find out what is work done (W) = ?

The standard formula to calculate work done is given by,

$:\implies\sf{w = f \times s \times cos \theta}$

$:\implies\sf{w = 20 \times 200 \times cos60}$

$:\implies\sf{w = 20 \times 200 \times \frac{1}{2} }$

$:\implies\sf{w = 20 \times 100 \times 1}$

$:\implies\sf{w = 2000J}$

• Total work done done by rope is 2000J.
