A ball is thrown vertically upwards with an initial velocity of 18.80 m/s, from the ground. How long is the ball in the air? (Neglect air resistance.) What is the greatest height reached by the ball? Calculate the time at which the ascending ball reaches a height of 12.8 m above the ground. A rocket, initially at rest on the ground, accelerates straight upward with a constant acceleration of 53.0 m/s^2, until the fuel is used up after 6.80s. What...

A stone used in the sport of curling has a mass of 18.0 kg and is initially at rest, sitting on a Flat ice surface. It is pushed with a constant force of magnitude 24.0N over a distance of 4.00 m. (You may assume that any friction between the stone and the ice is negligible.) (a) (i) What is the acceleration of the stone and what is the work done in accelerating it? (ii) By considering the conservation of energy...

A 15kg object falls a distance of 5.0 meters. How much work does gravity do on the object during this motion? Use the work-energy principle (from chapter 6- NO POTENTIAL ENERGY) to determine the speed of the object just as it reaches the ground. Assume there is no air resistance and the object starts from rest.

While standing at the edge of the roof of a building, a man throws a stone upward with an initial speed of 6.43 m/s. The stone subsequently falls to the ground, which is 11.7 m below the point where the stone leaves his hand. At what speed does the stone impact the ground? Ignore air resistance and use g = 9.81 m/s2 for the acceleration due to gravity. impact speed: m/s How much time is the stone in the air?...
