A car moves with uniform velocity of 40m/s for 5 s. It comes to rest in the next 10 s with uniform deceleration

Respuesta :

Answer:

-8 m/s²

Explanation:

Initial velocity = 40 m/s

Final velocity = 0 m/s

Time (T1) = 5 s

Time (T2) = 10 s

Acceleration = v - u/t2 - t1

Acceleration = 0 - 40/10 - 5

Acceleration = -40/5

Acceleration = -8 m/s²
