A weightlifter raises a 50kg weight to a height of 2m in 2 minutes. What was the power spent by the weightlifter?
Added by Patrick H.
Step 1
Work is given by the formula: Work = Force × Distance In this case, the force is equal to the weight of the object, which is given by: Force = Mass × Gravity where Mass = 50 kg and Gravity = 9.81 m/s² (approximately). So, Force = 50 kg × 9.81 m/s² = 490.5 Show more…
