The driver of a truck slams on the brakes when he sees a tree blocking the road. The truck slows down uniformly with acceleration −5.70 m/s2 for 4.20 s, making skid marks 57.2 m long that end at the tree. With what speed does the truck then strike the tree?
Homework Answers
Concept:- here we use equations of kinematics
to find the initial velocity and then we use it to find the final
velocity as shown below,

The driver of a car slams on the brakes when he sees a tree blocking the road. The car slows uniformly with acceleration of −5.00 m/s2 for 4.15 s, making straight skid marks 64.4 m long, all the way to the tree. With what speed (in m/s) does the car then strike the tree? i got 5.14 which is the the right answer but the second part im lost.. What If? If the car has the same initial velocity, and...
