Question

A car initially traveling 28.0m/s speeds up at a rate of 2.00 m/s^2. Determine all unknowns and answer the following questions. What was the car’s final speed? How far did the car travel during this time?

Answer 1

The problem cannot be determined or solved

Step-by-step explanation

This is the information we have:

• initial speed, v0 = 28 m/s

,

• acceleration, a = 2 m/s^2

We have to find:

• final speed, v

,

• final position, x

To find the final speed of an object we'd use the following formula:

`v=v_0+at`

And to find the distance an object traveled we'd use:

`x=x_0+v_0t+(1)/(2)at`

Note that for both we need to find how long the object was moving. In this problem, we don't have that information so we cannot determine the final speed or the distance the car traveled.

For example, the speed and distance at t = 2 seconds is not the same as at t = 20 seconds. Ideally, the car could keep speeding up indefinitely at the same acceleration.

Therefore, witht he given information the problem cannot be solved
