a slingshot fires a pebble from the top of a building at a speed of 14.0 m/s. the building is 31.0 m tall. air resistance is negligible. (a) calculate the speed with which the pebble strikes the ground when the pebble is fired horizontally. (b) calculate the speed with which the pebble strikes the ground when the pebble is fired vertically. (c) calculate the speed with which the pebble strikes the ground when the pebble is fired vertically straight down.
