3. a car is originally travelling at 15.0 meters per second on a straight horizontal road. the driver applies the brakes, causing the car to decelerate uniformly at 4.00 meters per second sqaured until it comes to rest. calculate the car's stopping distance .[ show all work , including the equations and substitutions with units ]

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

see earlier

b. false

explanation:

suppose a rock in free fall is dropped off a cliff. after falling for 5 seconds, its speed would not be 100 m/s.
