a child pulls a friend in a little wagon with constant speed. if the child pulls with the force of 16 n for 10.0 m and the handle of the wagon is inclined 25 degrees with respect to the horizontal, how much work does the child do on the wagon?

Respuesta :

The work done by the child on the wagon is 158.4 J

Work done is defined as the product of the force applied on the object and the component of distance traveled by the object in the direction of the force. Mathematically,

W = FdCosθ

where,

W = work done = ?

F = force applied = 16 N

d = displacement = 10 m

θ = angle of inclination = 25°

Therefore,

W = (16 N) (10 m)Cos(25°)

W = 158.4 J

Hence, work done by the child on the wagon is 158.4 J
