(Take g = 10 m/s 2). Solution: Height of each step = 20 cm =0.20 cm Height of 30 steps, H = 30 × 0.20 . Time, t = 15 seconds Force exerted by man against gravity F = Weight of man = mg The metric unit for work is a joule. A joule is equal to one Newton-meter, which is the amount of work needed to move a 1 Newton force a distance of 1 meter. When you divide work by time, you get power, measured in units of joules per second. This is also called a Watt.Q37. A body of mass 100kg is lifted up by 10m. Find: a) the amount of work done. b) potential energy of the body at that height. Answer: Height, h = 10m. Acceleration due to gravity, g = 10m/s 2. a) Work done, W = mgh = 10kJ. b) Potential energy of the body = work done = 10kJ. Q38. A boy weighing 50kg climbs up a vertical height of 100m.Click here👆to get an answer to your question ️ A man of mass 60 kg runs up a flight of 30 steps in 40 seconds, if each step is 20 cm height. Calculate its power. The ship goes by with a speed of 1 m/s and the guy on the ship exerts a 2 N force on a 1 kg mass, initially at rest in the ship, for 1 s. The acceleration is therefore F/m=2 m/s 2. The distance (in the ship) the mass travels is x = ½ at 2 = ½ x2x1 2 =1 m and the speed it ends up with is v=at=2x1=2 m/s. The work done is therefore W=Fx=2x1=2 J ...If you find yourself with episodes of diarrhea that do not resolve ...

ABG Shipyard, which exited the fight for Great Offshore by selling its entire stake and pricing its bid lower than rival Bharati Shipyard, has ended up with a 15% stake in the company. ABG's open offer was priced at Rs 520 per share against Bharati's Rs 590.An object of mass 3.00 kg is subject to a force E, that varies with the position as in the figure below. (a) Find the work done by the force on the object as it moves from x 0 to x = 5.00 m. (b) Find the work done by the force on the object as it moves from x 5.00 m to x = 12.0 m. 13 ton digger hireThe work done is equal to the change in kinetic energy. So if the net work done on an object is zero, its change in kinetic energy is also zero. Thus, the speed of the object will remain the same. Chapter 7 Work And Kinetic Energy Q.4P A farmhand pushes a 26-kg bale of hay 3.9 m across the floor of a barn.Height: 6'6" / 198.1 cm. Weight: 275 lbs. / 124.7 kg. DOB: 1973.
