Kinematics and two body problem

[From: ] [author: ] [Date: 12-02-27] [Hit: ]
5 m/s2.stop?Answer in units of s-This is really just a one-body problem involving the lead car.The other car does not participate in the breaking of the lead car at all.Basically, the lead car is moving at 24 m/s and decelerates at 1.......
Here's my second problem that i couldn't find the answer to

Two cars are traveling along a straight line in
the same direction, the lead car at 24 m/s and
the other car at 37 m/s. At the moment the
cars are 57 m apart, the lead driver applies the
brakes, causing the car to have a deceleration
of 1.5 m/s2.
How long does it take for the lead car to
stop?
Answer in units of s

This is really just a one-body problem involving the lead car. The other car does not participate in the breaking of the lead car at all.

Basically, the lead car is moving at 24 m/s and decelerates at 1.5 m/s^2 to zero. The time required is simply

( 24 m/s ) / ( 1.5 m/s^2 ) = 16 seconds
