Q. A bomb is dropped from an airplane in level flight at a velocity of 970 km/h. The altitude of the aircraft is 2000 m. At what horizontal distance from the initial position of the aircraft will the bomb land?
Q. A 692 g block is released from rest at height h0 above a vertical spring with spring constant k = 500 N/m and negligible mass. The block sticks to the spring and momentarily stops after compressing the spring 13.0 cm. How much work is done (a) by the block on the spring and (b) by the spring on the block? (c) What is the value of h0? (d) If the block were released from height 3h0 above the spring, what would be the maximum compression of the spring?
