QUESTION:
(III) Show that the equation for the stopping distance of a car is , where is the initial speed of the car, is the driver's reaction time, and is the constant acceleration (and is negative).
ANSWER:Solution 29P
Step 1 of 2
We have to show that the equation for the stopping distance of a car is
The stopping distance of a car can be found by using the kinematic equation for constant acceleration.
where,
final velocity = 0 m/s
initial velocity in m/s
= stopping distance in m
distance travelled by the car before
the brakes are applied in m
constant acceleration in m/s2
