the cases.
Example 6. Starting from a stationary position, a
car attains a velocity of 5 m/s in 20 s. Then, the
driver of the car applies a brake such that the
velocity of the car comes down to 3 m/s in the next
6 s. Calculate the acceleration of the car in both​

Answer 1

Answer:

Explanation:

case 1:

a=v-u/t=5-0/20=1/4=0.25m/s2

case2:

a=v-u/t=0-3/6=-1/2=-0.5m/s2
