What is the speed of the ball after it has traveled 1.10 m downward?A student is on the roof of the SP building, 15.0 m above the ground. Your physics instructor, who is 163 cm tall, is walking alongside the building at a constant speed of 0.35 m/s. If you wish to drop an egg on your instructors head, where should the instructor be when you release the egg? Assume the egg is in free fall and air friction is “negligible”.A tired cyclist on a bicycle (102.0 kg combined) starts with an initial velocity of 15.0 m/s at the bottom of a hill and coasts up the hill.
