The velocity of a car changes from 15 m/s south to 5 m/s south in 2
seconds. What is the acceleration of the car?
A. 5 m/s2 north
B. 10 m/s2 north
C. 10 m/s2 south
D. 5 m/s2 south

Respuesta :

Answer:

Acceleration of car = -5 m/s south

Explanation:

Given:

Initial velocity = 15 m/s

Final velocity = 5 m/s

Time taken = 2 sec

Find:

Acceleration of car

Computation:

Acceleration = Change in velocity / time

Acceleration of car = [5-15] / 2

Acceleration of car = -5 m/s south
