what power is expended in lifting a 50kg weight to a height of 20m in 1 minute
Added by Melissa A.
Step 1
First, we need to find the work done in lifting the weight. Work done (W) is given by the formula: W = m * g * h where m is the mass (50 kg), g is the acceleration due to gravity (approximately 9.81 m/s²), and h is the height (20 m). Show more…
