You are in a hot air balloon (yes, another balloon problem!) rising from the ground at a constant velocity of 2.20 m/s upward. To celebrate the takeoff, you open a bottle of champagne, expelling the cork with a horizontal velocity of 4.40 m/s relative to the balloon. When opened, the bottle is 6.40 m above the ground. (A)What is the initial speed of the cork, as seen by your friend on the ground? (B)What is the initial direction of the...

A water balloon is dropped from the top of the Physics building. Assume the balloon does not break when it strikes the ground.
A water balloon is dropped from the top of the Physics building. Assume the balloon does not break when it strikes the ground. a) Create a particular model for this phenomenon by making an energy-system diagram for the process that takes place from the time the water balloon is dropped until it is motionless on the ground. (Hint: consider the indicators to determine what energy systems must be present/can be excluded. Have you included enough systems?) b) If the water balloon is...
A student throws a water balloon with speed vo from a height h = 1.52 m at an angle θ=39° above the horizontal toward a target on the ground.
A student throws a water balloon with speed vo from a height h = 1.52 m at an angle θ=39° above the horizontal toward a target on the ground. The target is located a horizontal distance d = 7.5 m from the student's feet. Assume that the balloon moves without air resistance. Use a Cartesian coordinate system with the origin at the balloon's initial position. Part (a) what is the position vector, Rtarget that originates from the balloon's original position and...
