Q1. A ball is thrown directly up from the ground with speed vsub0. At the same time, a second ball is dropped from rest from a height H, straight above the point where the first ball was thrown upward. There is no air resistance. A) Find out the time at which the two balls collide. B) Find out the value of H in terms of vsub0 and g so that at an instant the balls collide, first ball is at the highest point of its motion.
Q2. Consider the vector with magnitude 5.00 at an angle 25.5 north of east. What is the x component of the vector?
