Answer:
It will decelerate at the rate of [tex]3.52\ m/s^2[/tex].
Explanation:
Initial speed of the truck, u = 35 m/s
Final speed, v = 5 m/s
Time, t = 8.5 s
We need to find the deceleration of the truck. As the speed is becoming less, it means it will decelerate. It can be calculated as follows :
[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{5-35}{8.5}\\\\a=-3.52\ m/s^2[/tex]
So, it will decelerate at the rate of [tex]3.52\ m/s^2[/tex].
