Answer:
the acceleration of the car is -5 m/s².
Explanation:
Given;
initial velocity of the car, u = 50 m/s
time of motion, t = 6 s
final velocity of the car, v = 20 m/s
The acceleration of the car is calculated as;
Therefore, the acceleration of the car is -5 m/s².
Power= work/time therefore 5000J/5s = 1000J/s or Watts
