Question

Find the force necessary to keep the toy car in equilibrium. The mass of the toy is 5kg and the inclination of the plane is 30°. Friction is neglected.

Answer 1

Given:

$\theta=30^{\circ}$

$m=5\:\rm kg$

The force required to keep the toy car in equilibrium

$$F=mg\sin\theta=5.0*9.8*\sin 30^{\circ}=25\:\rm N$$
