The horizontal surface on which the block (m = 2.0 kg) slides is frictionless. The speed of the block before it touches the spring is 4.0 m/s. How fast is the block moving at the instant the spring has been compressed 10 cm? k = 1500 N/m

An airplane flies horizontally with a speed of 500 m/s at an altitude of 350 m. Assume that the ground is level and there is no air friction. At what horizontal distance from a target must the pilot release a bomb so as to hit the target?

This reverse half circle lens is made out of glass (nglass = 1.5) and is surrounded by air (nair = 1.0). The surface on the left is flat. The radius of curvature on the right is R = 3 cm. For incoming rays from the left, what is the focal length of this lens?
