Starting from rest, a car accelerates for 8 seconds with a constant acceleration. during this time it travels 121 meters. find its velocity at the end of the 8 seconds.

The final velocity is

Step-by-step explanation:

The car starts from rest, this means the initial velocity U = 0.

The time interval is 8 seconds.

The total Distance traveled is 121 meters.

The formula for calculating final velocity(V) is,

a=

The final velocity is given by,

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
