Homework Help: Physics

Posted by Dawn on Sunday, October 16, 2011 at 6:44pm.

A motorist traveling at 15m/s encounters a deer in the road 38m ahead.

If the maximum acceleration the vehicle's brakes are capable of is -7m/s/s, what is the maximum reaction time of the motorist that will allow him or her to avoid hitting the deer?

Answer in units of s.

I have no clue how to solve this. There is also a part two to this question, which states:

If his or her reaction time is 1.44214s, how fast will he/she be traveling when he/she reaches the deer?

Answer in units of s.

Help would be greatly appreciated! <3
