At what angle should a water-gun be aimed in order for the water to land with the greatest horizontal range?

A car maintains a constant velocity of 100 km/hr for 10 seconds. During this interval it acceleration is:

A polar bear starts at the North Pole.  It travels 1.0 km south, then 1.0 km east, then 1.0 km north, then 1.0 km west to return to its starting point.  This trip takes 45 min.  What was the bear’s average velocity?

A girl throws a rock horizontally, with a velocity of 10 m/s, from a bridge.  It falls 20 m to the water below.  How far does the rock travel horizontally before striking the water?

A stone is released from rest from the edge of a building roof 190 m above the ground. Neglecting air resistance, the speed of the stone, just before striking the ground, is:

If   Vx = 6.80 units and   Vy = 7.40 units determine the magnitude and direction of V.
