Answer:

Explanation:
Given that,
A car accelerates negatively from 35m/s to 8m/s in 8s.
We need to find the car's acceleration.
Initial speed, u = 35 m/s
Final speed, v = 8 m/s
Time, t = 8 s
The acceleration of an object is equal to the rate of change of velocity. So,

Put all the values,

So, the acceleration of the car is equal to
.
