Question

A net force acting on a 5.0 kg box produces an acceleration of 4.2 m/s2. What

acceleration will the same net force cause on a 2.8 kg box?

Answer 1

7.5M/s^2

Explanation:

Answer 2

14 N

Explanation:

Let the mass of the box be m.

F = ma → F = 5 x 4.2 = 21 N

When mass = 2.8 kg, let the acceleration is a. For same force:

=> 21 = a x 2.8

=> 21/2.8 = a

=> 7.5 m/s² = a
