a crane lifts a marble block with a mass of 500kg to a height of 50metres in 2.5 minuteswhat is the power output of this crane? please help and explain your thinking thank you ! :)
2.5 minutes 150 seconds.power is in watt which is joules per seconds thus you use the mass and the height to find energy which is in joulesI believe it is potential energy! Umgh h being the height 50 m and m being the mass 50 kg and g is gravity which is 9.8 so U50509.8 24500 J so power is equal to 24500/150 163.33 W
