A cork shoots out of a champagne bottle at an angle of 36.0 ∘above the horizontal.
If the cork travels a horizontal distance of 1.50 m in 1.35 s , what was its initial speed?
Concept - The horizontal component of the velocity remains constant throughout the motion. We use this to find the initial speed using the angle, the time and the horizontal distance as shown below,

A cork shoots out of a champagne bottle at an angle of 35.0 above the horizontal. If the cork travels a horizontal distance of 1.30 m in 1.25 s, what was its initial speed?
Opening champagne. In a bottle of champagne, the pocket of gas (primarily carbon dioxide) between the liquid and the cork is at pressure of p = 5.07 atm. When the cork is pulled from the bottle, the gas undergoes an adiabatic expansion until its pressure matches the ambient air pressure of 1.00 atm. Assume that the ratio of the molar specific heats is γ = 4/3. If the gas has initial temperature T = 4.7°C, what is its temperature at...
A hot-air balloon is descending with a velocity of (−2.00m/s)y^. A champagne bottle is opened to celebrate takeoff, expelling the cork horizontally with a velocity of (5.00m/s)x^ relative to the balloon. When opened, the bottle is 5.50 m above the ground. part 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. part b) What is the speed of the cork...
Opening champagne. In a bottle of champagne, the pocket of gas (primarily carbon dioxide) between the liquid and the cork is at pressure of p = 2.98 atm. When the cork is pulled from the bottle, the gas undergoes an adiabatic expansion until its pressure matches the ambient air pressure of 1.00 atm. Assume that the ratio of the molar specific heats is γ = 4/3. If the gas has initial temperature T = 2.6°C, what is its temperature at...
Opening champagne. In a bottle of champagne, the pocket of gas (primarily carbon dioxide) between the liquid and the cork is at pressure of p = 5.30 atm, when the cork is pulled from the bottle, the gas undergoes an adiabatic expansion until its pressure matches the ambient air pressure of 1.00 atm. Assume that the ratio of the molar specific heats is γ-4/3. If the gas has initial temperature T-4.7°C, what is its temperature at the end of the...
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...
Artemis shoots an arrow at a target that is a horizontal distance d=65 m away: the bull's eye of the target is at same height of the arrow. At what angle in degrees above the horizontal must the arrow be released to hit the bull's eye if the arrows initial speed in 39 m/s?
When the dried-up seed pod of a scotch broom plant bursts open, it shoots out a seed with an initial velocity of 2.69 m/s at an angle of 30.0 ∘ below the horizontal. The seed pod is 0.470 m above the ground. How long does it take for the seed to land? What horizontal distance does it cover during its flight?
c) A dolphin leaps out of the water at an angle of 36° above the horizontal. The horizontal component of the dolphin's velocity is 9.0 m/s. Find the magnitude of the vertical component of the velocity. d.) A golf ball rolls off a horizontal cliff with an initial speed of 12.9 m/s. The ball falls a vertical distance of 15.5 m into a lake below. How much time does the ball spend in the air? Don't do this part, I...
A projectile is launched at an angle of 16.0° above the horizontal. What is its initial speed if it hits a target that is located a horizontal distance of 150 m from the launch point and 12.0 m above the launch level?
