For calculting the toal work done the weight of the man must be accounted. If only workdone for lifting the bag is required then the weight of the man will not be counted. Work done is given by W=F.displacement Now the toal force here is the weight of the man + weight of the bag therfore, F= 49+2 =51 Kg displacement = 100m W= 51*9.81*100=50031 J in water. Find the work done to haul the anchor and chain to the surface of the water from a depth of 25 ft. Break up the chain into segments of height h. If we have already removed hfeet of chain from the water, then the rest of the chain weighs 3(25 h) pounds. Of course, the anchor has constant weight of 100 pounds. 28 degrees. Mike is cutting the grass using a human-powered lawn mower. He pushes the mower with a force of 45 N directed at an angle of 41 degrees below the horizontal direction. Calculate the work that mike does on the mower each time he pushes it 9.1 m across the yard. 310 J. a 5.00 kg block of ice is sliding across a frozen pond at 2.00 m/s. A man weighing 50 kg lifts a weight of 30 kg to the top of building 10 m high. A man of mass 50 kg climbs up a ladder of height 10 m. Calculate: (i) the work done by the man, and (ii) the increase in his potential energy. Find the work done by the man. Take g = 10 m / s 2. View Solution. Q4. A man carrying a bag of mass 25 kg climbs up Part A Find the work done by the force \vec; A grocery cart with a mass of 19 kg is pushed at a constant speed along an aisle by a force F_P = 12 N which acts at an angle of 17 degrees below the horizontal. Find the work done by each of the forc; A 1.5-kg cart is pulled with a force of 7.3 N at an angle of 40 degrees above the horizontal. Work Done quiz for 5th grade students.

Multiple Choice. what is the weight of the crate? 1440 N. 90 N. 0.011 N. 14.4 N . Multiple Choice. The amount of power used is equal to the amount of work done over a given amount of time (P = W/t). To determine the amount of work done, you calculate the amount of force that is exerted over a given distance (W = f • d). (NOTE: The unit for power is the Watt, which is kg•m 2 /s 3) Example: Calculate the power generated by a 54 kg When the bottom 4.00-kg block is pulled to the left by the constant force P →, P →, the top 2.00-kg block slides across it to the right. Find the magnitude of the force necessary to move the blocks at constant speed. Assume that the coefficient of kinetic friction between all surfaces is 0.400. Work is done when an object moves in the same direction as the force is applied and also when force remains constant. This online Work Calculator helps you find out the work, force or distance based on the other two parameters. Work, force and distance are related to each other. A) the kinetic energy of the object. B) the gravitational potential energy of the object. C) the work done on the object by the force. D) the power supplied to the object by the force. b. The quantity 1/2 kx^2 is. A) the kinetic energy of the object. B) the elastic potential energy of the object. sBTkm.
