Calculate the acceleration in meters per second-squared, of a car moving at 10 m/s that accelerates to 24 m/s over a time of 7 second--

Respuesta :

Explanation:

v = u + at

24 = 10 + a * 7

24 = 10 * 7 a

a = 24 - 10/7

a = 14/7

a = 2m/sec^2

hope it helps you

Answer:

First calculate change in velocity:

final velocity = 20 m/s.

initial velocity = 30 m/s.

change in velocity = (20 - 30) = -10 m/s.

acceleration = -10 ÷ 25.

acceleration = -0.4 m/s 2

The acceleration value is negative here because the car is slowing down or decelerating.
