Question

A car can go from 0 m/s to 27 m/s in 4.5 seconds. If a net force of 6600 N acted on the car, what is its mass? (Hint: You must first calculate the acceleration then plug into Newton’s second law.)

Answer 1

Answer:

1100 kg

Explanation:

acceleration:

$a=(27-0)/4.5$

$a=6ms^{-2}$

Newton's second law:

$F=ma$

$6600=6m\\m=1100 kg$
