Help!
A car is moving with a velocity of 5 m/s changes to 15 m/s in 2 sec. Find
(i) Acceleration
(ii) Distance covered

Respuesta :

Answer:

5 m/s² & 20 m

Explanation:

#1

Acceleration = Final velocity - Initial velocity/Time

Acceleration = 15 - 5/2

Acceleration = 10/2

Acceleration = 5 m/s²

#2

v² - u² = 2as

(15)² - (5)² = 2(5)(s)

225 - 25 = 10s

200 = 10s

200/10 = s

20 = s
