PROBLEM 1: 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. PROBLEM 2: A ball is thrown vertically upward with a speed of 15 m/s. Determine the time of flight when it returns to its original position. PROBLEM 3: A particle travels along a straight line with an acceleration of a = (10 – 0.2s) m/s², where s is measured in meters. Determine the velocity of the particle when s = 10 m if v = 5 m/s at s = 0.

PROBLEM 1: 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.
PROBLEM 2: A ball is thrown vertically upward with a speed of 15 m/s. Determine the time of flight
when it returns to its original position.
PROBLEM 3: A particle travels along a straight line with an acceleration of a = (10 – 0.2s) m/s², where
s is measured in meters. Determine the velocity of the particle when s = 10 m if v = 5 m/s at s = 0.
PROBLEM 4: A particle moves along a straight line such that its acceleration is a = (4t? – 2) m/s²,
where t is in seconds. When t = 0, the particle is located 2 m to the left of the origin, and when t = 2 s, it
is 20 m to the left of the origin. Determine the position of the particle when t = 4 s.
