1. a car increases it's velocity from 0 m/s to 14 m/s in 2 seconds.
what is the acceleration

7 m/s²

We are given;

We are required to calculate th acceleration of the car;

In this case;

Acceleration = (14 m/s - 0 m/s) ÷ 2 seconds

                      = 7 m/s²

Therefore, the acceleration of the car 7 m/s²

the answer is learned

the dependant variable is spilled water

the independent is the heat
