A force of 50.0 N directed to the right acts on an object with a mass of 10.0 kg. Friction is 30.0 N. What is the magnitude of the resultant acceleration of the object

A force of 500 N directed to the right acts on an object with a mass of 100 kg Friction is 300 N What is the magnitude of the resultant acceleration of the obje class=

Respuesta :

Force = F = 50 N (right)

mass = m = 10 kg

Friction force = Fr = 30N

a = acceleration

Apply Newton's Second Law:

∑F = m a

F - FR = m * a

replacing:

50 - 30 = 10 * a

20 = 10 *a

20/10 = a

a = 2 m/s^2
