Question

3. A driver decreases the speed of a car from 25 ms to 10 m/s in 5 seconds. Find the acceleration of the car


​

Answer 1

Answer:

u = 25m/s

v = 10 m/s

time = 5 seconds

acceleration = (v-u)/t

= (10 - 25)/ 5

= -15/5

= -3

hence acceleration is -3.

Answer 2

Answer.15 ms

Explanation: because driver decrease the speed of car 25 duty to 10 metre we can minus 10 from 25 the the acceleration of the car is 15 ms
