Answer 1

The distance in meters traveled by the drag racer in 6 seconds is 180.

Step-by-step explanation:

Given:

A drag racer starts from rest. So, initial velocity of the drag racer,
`v_i=0`

Time taken is,
`t=6\ s`

Acceleration of the drag racer is,
`a=10\ m/s^2`

Now, we are asked to find how far will he reach in 6 seconds. So, we are asked the displacement, 'd'.

We use the following kinematic equation to find 'd'.

`d=v_it+(1)/(2)at^2`

Plug in the given values and solve for 'd'. This gives,

`d=0+(1)/(2)(10)(6)^2\\d=5* 36\\d=180\ m`

Therefore, the distance in meters traveled by the drag racer in 6 seconds is 180.
