Arace car has a speed of 80 m/s when the driver releases a drag parachute. if the parachute causes a deceleration of 4m/s^2, how far will the car travel before it stops?

The car travels 800m

Explanation:

We will need two formulas to solve this question:

We can obtain the the time by using the final velocity formula and replacing with known values:

Since we know the time, the question will be answered by inputing all the variables needed in the distance formula:

the answer is a. hope this .

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
