Question

a child pulls a car through a distance of 10meters on a smooth, horizontal floor. the string held in child's hand makes angle of 60° with the horizontal surface. if the force applied by the child be 5N, calculate the work done by the child in pulling the toy car​

Answer 1

Answer:

hi dear...

Explanation:

given, force F=5N

distance s=10m

engle between the toy car and the ground =60degree

therefore, Work done W=Fscos60

W=5x10cos60

W=50x0.5

W=25joules

have a nice day
