Acar's velocity changes from 0 m/s to 40 m/s in 5 seconds. what is the average acceleration of the car? (show work)

Acceleration,

Explanation:

Given that,

Initial velocity of the car, u = 0

Final velocity of the car, v = 40 m/s

Time taken, t = 5 s

Let a is the acceleration of the car. It can be calculated using first equation of motion as :

v = u + at

v = at

40 = a × 5

So, the acceleration of the car is . Hence, this is the required solution.

c) up is the direction the magnetic force is acting on the charge.
