Do you guys know what would be the curve looks like in the acceleration versus velocity graph? (including the air resistance when an object is falling) Thank you!

A ball is thrown vertically upwards with an initial velocity of 27.0 m/s. Neglecting air resistance, how long is the ball in the air? What is the greatest height reached by the ball? And calculate the first time when the ball has half of its initial velocity. Thank you!

A flowerpot sails first up and then down past an open window. The pot is in view for .5 sec and the height of the window (top to bottom) is 2 m. how high does the flowerpot go?

A football is thrown toward a receiver with and initial speed of 20 m/s, at an angle of 30 degrees above the horizontal. At the instant, the receiver is 20 meters from the quarterback. In what direction and with what constant speed should the receiver run in order to catch the football at the level...
