What is the magnitude of the acceleration that is produced when the brakes of a 2.4 x 103 kg car apply a 3.2 x 103 n force to stop the car?

a .75 m/s2

b 1.3 m/s2

c 5.6 x 103 m/s2

d 7.7 x 106 m/s2

B 1.3 m/s2

Explanation:

Newton's second law of motion states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force. This in form of an equation is F = m*a

Since you want to know the acceleration, you have to solve for a

F = m*a

a = F / m

and now you substitute the data

a = 3.2x10^3 N / 2.4x10^3 kg

a = 1.3 m/s^2
