Question

The velocity of a car changes from 50 m/s to 20 m/s within 60s .. calculate the acceleration of the car?/​
1) 1 m/s^2
2) _0.5 m/s^2
3) 0.5m/s^2

Answer 1

Answer:

IF THIS IS HELPFUL THEN THANK AND RATE

Answer 2

Answer:

2)-0.5m/s

Explanation:

for car velocity is decreased 50m/s to 20m/s. intial velocity (u)=50m/s,final velocity (v)=20m/s, time taken=60s. acceleration (a)=? a=v-u/t=20-50/60=-30/60=-1/2=-0.5m/s
