Question

The speed of a car reduces 15 m/s to 5 m/s over a displacement of 10 m what is the acceleration of the car​

Answer 1

Explanation:

Initial velocity = u = 15 m/s

Final velocity = v = 5 m/s

Displacement = s = 10 m

Acceleration = a = ?

v² - u ² = 2as

(5²) - (15²) = 2a (10)

25 - 225 = 20a

a = -220 / 20

a = - 10 m/s²
