Question

A force of 20 N displays a body through a distance of 1 m at an angle of 60° from its own direction. Calculate the amount of work done.

Answer 1

Given

Force (F) = 20 N

Displacement (s) = 1 m

Angle between force and displacement θ = 60°

★ Work (W) = Fs cos θ

= 20 × 1 × cos 60°

= 20 × 1 × ½

= 10 J

Answer 2

hey mate!!

here's your answer

A force of 20 N displaces a body through a distance of 1 mat an angle of 60° from its own direction. Calculate the amount of work done.

A force of 20 N displaces a body through a distance of 1 mat an angle of 60° from its own direction. Calculate the amount of work done.Here, force F = 20 N, displacement, s = 1 m.

A force of 20 N displaces a body through a distance of 1 mat an angle of 60° from its own direction. Calculate the amount of work done.Here, force F = 20 N, displacement, s = 1 m.Angle between force and displacement 0 60°.
