Q1) Initially, the car travels along a straight road with a speed of 35
m/s. If the brakes are applied and the speed of the car is reduced to 10
m/s in 15 s, determine the constant deceleration of the car.
Q2) A car starts from rest and with constant acceleration achieves a
velocity of 15 m/s when it travels a distance of 200 m. Determine the
acceleration of the car and the time required.
Q3)A train starts from rest at a station and travels with a constant
acceleration of 1 m/s. Determine the velocity of the train when t = 3s
and the distance traveled during this time.
Q4) car is traveling at 15 m/s, when the traffic light 50 m ahead turns
yellow. Determine the required constant deceleration of the car and
the time needed to stop the car at the light.
Q5) Car A starts from rest at t 0 and travels along a straight road
with a constant acceleration of 6 ft/s until it reaches a speed of
80 ft/s. Afterwards it maintains this speed. Also, when t-0, car B
located 6000 ft down the road is traveling towards A at a constant
speed of 60 ft/s. Determine the distance traveled by car A when they
pass each other.
