Question

a car starts from 20 seconds is travelling 10 /m per second . what is the acceleration ?​

Answer 1

Answer:

2m/s² or -2m/s²

Step-by-step explanation:

am not sure if it is negative

Answer 2

Answer:

Initial velocity (u)= 0

final velocity(v) = 10m/s

time (t) = 20s

now, we have

acceleration = v-u/t

a = 10m/s-0m/s divided by 20s

acceleration=2ms
