(a) What is the average useful power output of a person who does 6.00106J of useful work in 8.00 h? (b) Working at this rate, how long will it take this person to lift 2000 kg of bricks 1.50 m to a platform? (Work done to lift his body can be omitted because it is not considered useful output here.)
A baseball is thrown from the roof of h = 21.8-m-tall building with an initial velocity of magnitude 14.0 m/s and directed at an angle of 53.1 above the horizontal. a) What is the speed of the ball just before it strikes the ground? Use energy methods and ignore air resistance. b) What is the answer for part (A) if the initial velocity is at an angle of 53.1 below the horizontal? c) If the effects of air resistance are included, will part (A) or (B) give the higher speed?
In the Marvel comic series X-Men, Colossus would sometimes throw Wolverine toward an enemy in what was called a fastball special. Suppose Colossus throws Wolverine at an angle of θ = 31.5° with respect to the ground (see figure below). Wolverine is d = 2.08 m above the ground when he is released, and he leaves Colossus's hands with a speed of vi = 18.2 m/s. (a) Using conservation of energy and the components of the initial velocity, find the maximum height attained by Wolverine during the flight. _____m (b) Using conservation of energy, what is Wolverine's speed the instant before he hits the ground? ______ m/s
i) A plane has a take-off speed of 88.3 m/s and requires 1365 m to reach that speed. Determine the acceleration of the plane and the time required to reach this speed. ii) When the speed of an object doubles, does its kinetic energy double? Explain youranswer?
A 2.75-meter-long log on a panda sanctuary leans on an almost vertical rock wall and it makes 30⁰ angle with the vertical rock wall. If a 75 kg panda climbs the log, a) compute the work done by gravity on the panda. b) Does the answer to part (a) depend on whether the panda climbs at constant speed or accelerates up the log?
A physics professor wants to build a spring-based nerf launcher. (a) Ignoring air resistance (which would be a bad idea in this case), if the launcher is to have a range of 100 m when fired at an angle of 45°, then what would the muzzle velocity of the launcher need to be? (b) Given that a nerf dart is about 1 gram, what would be the kinetic energy of the dart as it leaves the launcher? (c) If launcher's spring is compressed 20 cm prior to firing, then what would the spring constant of the spring used in the launcher need to be? Solve part (a) using kinematics since the time is your linchpin between the horizontal and vertical motion
Continue with pic Considering this, what impact would a half‑pound rock traveling at the calculated speed likely have on someone if it struck them in the forehead? A. The impact would likely cause serious injury. B. The impact would hurt a little but would likely not cause any injury. Suppose David missed. What distance dd would the rock travel before striking the ground if David released it from a height of H=4.95 ft?H=4.95 ft? Assume there is no air friction. Can someone help with this? I can't even understand the question. Thanks
