A bucket begins weighing 15 pounds, including the sand it holds. The bucket is to be lifted to the top of a 30 foot tall building by a rope of negligible weight. However, the bucket has a hole in it, and leaks 0.3 pounds of sand each foot it is lifted. Find the work done lifting the bucket to the top of the building in foot-pounds. A block of mass 1 kg slides down on an inclined plane with the angle of inclination of 30 0. Find the work done as the block slides through 50 cm. Find the work done by the block's weight as it slides through 50 cm. Find the work done against friction as the block slides through 1m. View Solution. Q4. A block of mass 250 g slides down You push a 15 kg box of books 2.0 m up a 25 o incline into the back of a moving van. The box moves at a constant velocity if you push it with a force of 95 N. Find a) the work done by normal force on the box, b) the work done by your push on the box, c) the work done by gravity on the box, and d) the work done by friction on the box. If the value of g be 10 m s−2, the work done by her after climbing 2 m will be: Calculate the work done in lifting 200kg of water through a vertical height 6meters. A weightlifter is lifting weights of mass 200 kg up to a height of 2 metres. If g = 9.8 m s −2, calculate : (a) potential energy acquired by the weights. Find the work done when a 25 kg weight is (i) lifted to a vertical height of 2.0 m from the ground, (ii) carried to the same place by pushing it up an inclined plane making an angle of 30 with Variables in the Weight Equation \( W \) = weight \( m \) = mass \( g \) = gravity (acceleration due to the pull of gravity) The Weight Calculator uses the formula W = mg, or weight W is equal to mass m times gravity g.Note that the standard units for weight calculations are N, kg and m/s 2.If you enter other units of measure for your calculation the calculator will do the units conversion for The changes in specific internal energy across the compressor is 82 KJ/kg and the heat loss by cooling is 24 KJ/kg. Neglecting changes in kinetic and potential energies, find the work in KW. 32. Calculate the change of entropy per kg of air when heated from 300 K to 600 K while the pressure drops from 400 Kpa to 300 KPa. 8910F.
