Which has a higher acceleration:a 10kg object acted upon with a net force of 20N or an 18kg object acted on by a net force of 20N

Answer: The acceleration of 10 kg object is greater than that of 18 kg object.

Explanation:

According to Newton's Second law:

F = ma - - - (A)

Let's find the acceleration for both 10 kg and 18 kg objects!

The net force on both of these masses = F = 20N

(1) Acceleration of 10 kg object

Mass = m = 10 kg

Plug in the values in equation (A):

20 = 10 * a

Acceleration = a = 2 m/s^2

(2) Acceleration of 18 kg object

Mass = m = 18 kg

Plug in the values in equation (A):

20 = 18 * a

Acceleration = a = 1.11 m/s^2

2 > 1.11; therefore, 10 kg object has the higher acceleration compared to the acceleration of the 18 kg object.
