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

1100 kg

Step-by-step explanation:

acceleration:

`a=(27-0)/4.5`

`a=6ms^(-2)`

Newton's second law:

`F=ma`

`6600=6m\\m=1100 kg`
