Bianca throws a football from the edge of a cliff at a height of 22 m at a velocity of 18 m/s [40 above the horizontal]. Nelson is at the bottom of the cliff 12 m away from the base of the cliff. Assume zero air resistance.

a. Determine the horizontal range of the football.

b. If Nelson can run at a maximum constant speed of 6.0 m/s, is it possible for Nelson to catch the ball before it hits the ground? Support your answer with calculations.

Q#2. A car of travels around a banked curve of radius 85 m. The car maintains a speed of 22 m/s around the track.

a. What must the banking angle be for the car to travel safely around the curve, if the road were frictionless? Include a free-body diagram of the car as soon from the back view.

b. Explain what happens if the car goes faster than 22 m/s; if the car goes slower than 22 m/s
