Please answer these two questions.
A boy fires a pebble using a slingshot. The target is shoulder-high and 30.0 m distant. After several at- tempts he finds that to hit the target, he must aim at a point 4.30 m above the target. What is the speed with which the pebble leaves the slingshot? 4A small plane cruises with an airspeed of 280 km/h. If its destination is due north and a 60.0-km/h wind is blowing from the northeast, what...
