(1 point) How much work is required to lift a 1500-kg satellite to an altitude of 1.100 m above the surface of the Earth? The gravitational force is F=GMm/r2, where M is the mass of the Earth, m is the mass of the satellite, and is the distance between the satellite and the Earth's center. The radius of the Earth is 6.4. 100 m, its mass is 6 . 1024 kg, and in these units the gravitational constant,...
How much work is required to lift a 5-kg dog 3 meters high and hold her at that height for an hour?
you lift a 2 kg box from the first to the second floor of a building by climbing the stairs and perform 300j of work. how much work is needed to lift the box, straight up vertically, from the first to the second floor of the same building
13. How much power does it take to lift 30.0 kg 10.0 m high in 5.00 s?
You plan on using a
5000-kg-crane to vertically lift a very heavy mass (m), as shown in
the figure. Assume the horizontal location of the crane’s center of
mass is halfway between the front and rear bumper of the crane. (a)
What is the largest mass that can safely be lifted without the
crane tipping over? (b) If the maximum mass is lifted vertically,
what is the maximum height it can be lifted without tipping the
crane over? (Use 4...
Calculate the Amount of Work Done to Lift an Object and Cable Question We use a rope with a linear mass density of 20 kg/m to lift a block of cement weighing 1000 kg 50 meters above the ground. The rope is 75 meters long but we need an additional 100 meters to secure the concrete block so it can be lifted safely. Find the total amount of work done (in kilojoules, remembering that (1 kJ = 1000 J). Do...
You work at a garden store for the summer, and you lift a 15 kg bag of fertilizer with a force of 235 N. a) What is the magnitude of the acceleration of the fertilizer bag? (m/s2) b) How much does the fertilizer bag weigh? (N)
7. A flatbed truck is loaded with a stack of cement whose combined masses is 1143.5 kg. The coefficient of static friction between the bad of truck and the bottom sack in the stack is 0.372, and the sack are not tied down but held in place by the force of friction between the bed and the bottom sack. The truck acceierates unifommy from rest to 91.08 km/h in 22.9 s. The stack of sacks is 1 m from the...
