Acar accelerated from 45 m/s to 0 m/s in 10 seconds. what is the average acceleration of the car?

Average acceleration is- 4.5

Given:

= 45 m/s

= 0 m/s

t = 10 s

To find:

Average acceleration = ?

Formula used:

Average acceleration =

Solution:

Average acceleration is given by,

a = =

a =

a = - 4.5

Thus average acceleration is - 4.5 . Negative sign shows that it is deceleration.

are there options? cause you ain’t. real specific

v=ir = 3x15 =45 v
