When a drag strip vehicle reaches a velocity of 60 m/s, it begins a negative acceleration by releasing a drag chute and applying its brakes. While reducing its velocity back to zero, its acceleration along a straight line path is a constant -7.5 m/s2. What displacement does it undergo during this deceleration period?

• Physics -

Vf^2=Vi^2+2ad solve for d.

I think I am plugging the problems in wrong I am not getting the correct answer?

• Physics -

How can I know how you are "plugging"?

"Plug" this into the google search window:

60^2/(2*7.5)=

That worked. Thank you
