1. How long will it take for the cannon ball to land?2. How far from the base of the cliff will it land?3. What was the vertical velocity when it landed?4. What was the horizontal velocity when it landed?
What is magnitude of the speed of the boat
What is the ratio of the amplitude of the damped oscillation
An airplane with a mass of 2.6*10^6 kg. has the air flow past the lower surface of the wings at 100 m/s. If the wings have a surface area of 1200 m2, how fast should the air flow over the upper surface of the wing if the plane is to stay in the ai..

Compute the acceleration of a 0.55m diameter car tire while the car is travelling at a constant speed of 25m/sec. b. compare this with the acceleration experienced by a jet car tire diameter 1 when setting a land speed record of 310m/sec.
Find out the magnitude of the vertical component of the velocity
