Answer:
72 kilometres per hour
Explanation:
The formula for calculating speed is distance/time.
So to work this out you would convert 2 minutes into hours. You would divide 2 by 60 to convert it into hours. This is because the standard unit for speed with kilometres is kilometres per hour. Then you would divide 2.4 by that.
1)Divide 2 by 60:

2) Divide 2.4 by 0.0333333.

3) Round it.

Force = mass x acceleration
Force = 4kg x 10m/s^2
Force = 40N
