Question

8.

How long (in seconds) does it take for a car
accelerating at 3.50 m/s2 to go from rest to 120 km/h?

Answer 1

9.5 seconds

Step-by-step explanation:

You need to make the ending speed into meters per sec.

So it would be 120km/h = 33.33m/s

If the acceleration rate is 3.5m/s, then the final answer would equal to 9.5 seconds

Also btw rounding it up is a good idea too so 10 seconds if you round
