Question

16. A pug puppy is sitting on a skateboard. The pug has a mass of 2.4 kg, and the skateboard has a mass

of 1.3 kg. Assuming the pug stays on the skateboard, what force would give the pug and skateboard an
acceleration of 3.2 m/s?? You may ignore friction. Be sure to follow significant digit rules.

Answer 1

12 N

Step-by-step explanation:

Use Newton's second law:

∑F = ma

F = (2.4 kg + 1.3 kg) (3.2 m/s²)

F = 11.84 N

Rounded to two significant figures, the force is 12 N.
