Given:
A car pulls a toy to distance of 10m and the string makes an angle of 60 degree with the horizontal. Let force be 10
To find:
Calculate the work done by the child in pulling the toy car.(Take cos 60 degree =0.5).
Solution:
From given, we have,
Force F = 10N
Distance s = 10m
The angle between the toy car and the ground = 60degree
Work done W = Fscos θ
W = 10 × 10 cos60
W = 100 × 0.5
W = 50 J
Therefore, the work done by the child in pulling the toy car is 50 J
