Question

An object has an acceleration of 12.0 m/s/s. If the mass of this obiect were tripled (with no change in its net force), then its new acceleration would be

m/s/s.

Answer 1

4.00 m/s/s

Step-by-step explanation:

Newton's second law of motion:

F = ma

Initially, the acceleration is 12.0 m/s/s.

F = m (12.0)

F = 12m

Next, the mass is tripled, but the net force stays the same.

F = ma

12m = (3m) a

a = 4

The new acceleration is 4.00 m/s/s, or one third of the initial acceleration.
