- Homework Statement
- A car is traveling at 25.8 m/s when the driver notices that

the bridge is out 150 m ahead. If the driver applies the brakes

quickly with a uniform acceleration rate of - 2.55 m/s^2

, will the car stop before the cliff and if so how far from the edge will

the car be?

b. How long will it take for the car to stop through the last 35.6 m of

it's motion?

- Relevant Equations
- d = vi * t + 1/2at^2

t= v/a

=25.8 m/s / -2.5 m/s^2

=10.1 s

therefore,

d= vi * t + 1/2at^2

= (25.8)(10.1) +1/2(-2.55)(10.1)^2

=131 m

I got the first one right I think, but I don't know how to do b

=25.8 m/s / -2.5 m/s^2

=10.1 s

therefore,

d= vi * t + 1/2at^2

= (25.8)(10.1) +1/2(-2.55)(10.1)^2

=131 m

I got the first one right I think, but I don't know how to do b
