Kinematic problems!
hi there,here is my problem
The police observe that the skid marks of a stopping car are 200m long. Assuming the car decelerated at a constant rate of 20m/s^2,skidding all the way, how fast was the car going when the brakes were applied?
i think we can solve the problem by using the physics equation v^2=u^2+(2*(a*s))...and
i try to use integration but the time interval isn't given so i am just looking for an alternative way to solve this problem...by the way ,this is a calculus assignment.
thx
