Answer 1

Answer:

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

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'.

$d=v_it+\frac{1}{2}at^2$

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

$d=0+\frac{1}{2}(10)(6)^2\\d=5\times 36\\d=180\ m$

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