For one particular event during the World's Strongest Man competition, Hafþór Júlíus Björnsson,who played Gregor Clegane on Game of Thrones, had to toss a 22.0 kg keg over a wall.If Björnsson took 0.827 s to açcelerate the keg from rest to 10.8 m/s while also raising it 1.12 m,what was his average power output (in W) during the toss? Captain Cutshaw is a 75.9 kg astronaut on board an experimental space station that orbits theMoon at an altitude of 269 km above the Moon's surface.Since the mass and average radius of the Moon are 7.350 x 1022 kg and 1740 km, respectively,how large must the gravitational force (in N) be that acts on Captain Cutshaw?

Since both questions are different, as per bartleby guidelines I can answer only 1st. Thanks!…

When its 75 kW (100 hp) engine is generating full power, a small single-engine airplane with mass 700 kg gains altitude at a rate of 2.5 m/s 1150 m/min, or 500 ft/min2. What fraction of the engine power is being used to make the airplane climb? (The remainder is used to overcome the effects of air resistance and of inefficiencies in the propeller and engine.)
For exercise, an athlete lifts a barbell that weighs 400 N from the ground to a height of 2.20 m at a constant speed in a time of 1.60 s. What is the metabolic energy, in kJ (kiloJoule)? Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
A record was set for stair climbing when a man ran up the 2300 steps of the Empire State Building in 13 minutes and 15 seconds. If the height gain of each step was 0.2 m, and the man's mass was 55.0 kg, what was his average power output during the climb?
Explorers in the jungle find an ancient monument in the shape of a large isosceles triangle as shown in the figure below. The monument is made from tens of thousands of small stone blocks of density 3 293 kg/m. The monument is 14.0 m high and 64.0 m wide at its base and is everywhere 2.50 m thick from front to back. Before the monument was built many years ago, all the stone blocks lay on the ground. How much work did laborers do on the blocks to put them in position while building the entire monument? Note: The gravitational potential energy of an object-Earth system is given by U, = Mgy CM, where M is the total mass of the object and yCM is the elevation of its center of mass above the chosen reference level.

A typical human brain has a mass of 1.4 kg, which makes up about 2% of a person's mass. However, the brain requires 20% of the body's power consumption. In essence, the brain requires 10 times as much power as any other organ in the body. The average power output of the human brain is about 2.0 × 10¹ W. Assume that the brain's power output could be converted into mechanical work and calculate how high we could use this power to lift an apple (m = 0.20 kg) in one minute. Number pa Units
