A catapult gives a rock a vertical velocity of 122m/s.
a. Determine the time the rock is in the air.
b. Determine the maximum height the rock would reach.
c. As the rock leaves the catapult the rock also has a horizontal velocity of 34m/s. solve for the rocks range.
d. Solve for the resultant velocity that the rock would impact the ground with.
