The acceleration of the car over the 2 minutes is 0.07 m/s².
Acceleration of the car
The acceleration of an object is the rate of change of velocity of the object with time.
Acceleration of the car over the 2 minutes
The acceleration of the car over the 2 minutes is calculated as follows;
a = Δv/t
a = (v - u) / t
where;
- v is the final velocity = 80 km/h = 22.22 m/s
- u is the initial velocity = 50 km/h = 13.89 m/s
- t is the time of motion, = 2 mins = 120 s
a = (22.22 - 13.89) / 120
a = 0.07 m/s²
Thus, the acceleration of the car over the 2 minutes is 0.07 m/s².
