A truck of passanger car applied breaks at a velocity of 30m/s and comes to rest res 5second later what is the acceleration
To find the acceleration, we can use the equation:
acceleration = change in velocity / time
In this case, the initial velocity (u) is 30 m/s and the final velocity (v) is 0 m/s (since the truck comes to rest). The time (t) is 5 seconds.
Therefore,
acceleration = (0 - 30) m/s / 5 s
acceleration = -30 m/s / 5 s
acceleration = -6 m/s²
So, the acceleration of the truck is -6 m/s². The negative sign indicates that the truck is decelerating.
