In this problem, we are required to calculate the constant acceleration and velocity before impact.
This is a Kinematics problem since it involves initial velocity, v0, acceleration, a, distance covered Δx, and time, t.
We'll follow the following simple steps!
We need to remember the four kinematic equations in order to solve the problem. These are:
A car traveling 56.0 km/h is 24.0 m from a barrier when the driver slams on the brakes. The car hits the barrier 2.00 s later.
(a) What is the magnitude of the car’s constant acceleration before impact?
(b) How fast is the car traveling at impact?
