Predict/Calculate A hot-air balloon rises from the ground with a velocity of (2.00 m/s) y ^ . A champagne bottle is opened to celebrate takeoff, expelling the cork horizontally with a velocity of (5.00 m/s) x ⌢ relative to the balloon. When opened, the bottle is 6.00 m above the ground. (a) What is the initial velocity of the cork, as seen by an observer on the ground? Give your answer in terms of the x and y unit vectors. (b) What are the speed of the cork and its initial direction of motion as seen by the same observer? (c) Determine the maximum height above the ground attained by the cork. (d) For what amount of time does the cork remain in the air?

Cam mechanisms are used in many machines. For example, cams open and close the valves in your car engine to admit gasoline vapor to each cylinder and to allow the escape of exhaust.
The principle is illustrated in the figure below, showing a follower rod (also called a pushrod) of mass m resting on a wedge of mass M. The sliding wedge duplicates the function of a
rotating eccentric disk on a camshaft in your car. Assume that there is no friction between the wedge and the base, between the pushrod and the wedge, or between the rod and the guide
through which it slides. When the wedge is pushed to the left by the force F, the rod moves upward and does something such as opening a valve. By varying the shape of the wedge, the
motion of the follower rod could be made quite complex, but assume that the wedge makes a constant angle of 0 = 15.0°. Suppose you want the wedge and the rod to start from rest and
move with constant acceleration, with the rod moving upward 1.00 mm in 8.00 ms. Take m…
