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.
In this case, we can find the magnitude by multiplying M × A = 0.5 × 0.7 = 0.35 Newtons. 4. Multiply Force × Distance. Once you know the magnitude of the force acting on your object and the distance it's been moved, the rest is easy. Simply multiply these two values by each other to get your value for work.
Work equals force times distance and kinetic energy equals one-half the mass of the object times its velocity squared, so: W = F d = 1 2 m v 2. W=Fd=\frac {1} {2}mv^2 W = F d = 21. . mv2. Substitute the measurements for force, distance and mass into the equation.
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
