A rock of mass 2.0 kg is thrown upwards from the ground and its reaches a height of 15.0 m (it is not the max height!) where its speed is 25.0 m/s. a) Find the work done by gravity up to 15.0 m of upwards displacement. b) Find the rock’s speed as it leaves the ground using the work-kinetic energy theorem. c) Find the max height it reaches
inclass-ME conservation-Wed, 10/25/2017 PM Name A stone of mass 0.75 kg is carried from the ground to the roof of a 25 m tall building. The stone is then dropped from the roof and falls to the ground along a path that is vertical only. Consider the ground as the zero point of potential energy. 1. What is the total ME of the stone at rest on the ground before it is carried to the roof? 2. What is the...
A player hits a tennis ball close to the ground with an initial velocity of 32 m/s at an angle 35˚ from the horizontal. Assume air resistance is negligible. a) If the opponent doesn't hit the ball, how long will the ball be in the air? b) What is the ball's velocity at the highest point in its trajectory? c) How high will the ball go? Please show all work and steps
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 thrown horizontally from the top of a 24-m tower hits the ground at a point 18 m from the base of the tower. (Ignore any effects due to air resistance.) (a) Find the speed at which the stone was thrown. (b) Find the speed of the stone just before it hits the ground.
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 stone thrown horizontally from the top of a 22-m tower hits the ground at a point 20 m from the base of the tower. (Ignore any effects due to air resistance.) (a) Find the speed at which the stone was thrown m/s (b) Find the speed of the stone just before it hits the ground m/s eBook
(1 point) A stone thrown upward from the top of a 72 ft cliff at 119 ft/s eventually falls to the beach below. (For this problem take the acceleration due to gravity to be g-32 ft/s2; take upwards to be a positive direction.) (a) How long does the stone take to reach its highest point? time (include units) (b) What is its maximum height? height- include units) (c) How long before the stone hits the beach? time (include units) (d)...
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?...
