Question

Q.1 A truck moving with a speed of 35 m/s stops after 7 seconds when breaks are applied. Calculate
the acceleration produced in the truck.​

Answer 1

v=0m/s

u=35m/s

t=7s

a=(v-u)/t

a=0-35/7=-5m/s^2

The negative sign is because of the deceleration.

Answer 2

Answer:

a = -5m/s^2 is right answer
