Guys here's your prob set (though i'll announce it sa class natin)- Physics Giancoli Chapter about Kinematics in 1D (pakihanap na lang yung pages):
22. A car travelling at 90 km/h decelerates at a constant 1.6 m/s2. Calculate (A) the distance the car goes before it stops, (b) the time it takes to stop, and (c) the distance it travels during the first and third seconds.

27. A person driving her car at 50 km/h approaches an intersection just as the traffic light turns yellow. She knows that the yellow light lasts only 2.0 seconds before turning red, and she is 30 m away from the near side of the intersection. Should she try to stop, or should she make a run for it? The intersection is 12m wi, and her car's maximum deceleration is -6.0 m/s2. Also her car takes 7.0s to accelerate from 50 km/h to 70 km/h. Ignore the length of her car and her reaction time.
31. (a) How long does it take a brick to reach the ground if dropped from the height of 50.0 m? (b) What will be it's velocity before it reaches the ground?
32. A baseball is thrown vertically into the air with a speed of 24.0 m/s (a) How high does it go?
