# A weightlifter lifts 240 kg from the ground to a height of 2.5 in 3 second. The average power is :A. 1960 WB. 19.6 KWC. 1.96 MWD. 196 W

Given,

Mass = 240 kg

Height = 2.5 m

Time = 3 s

Let g = 9.8 ms-2

We know,

Energy consumed = m × g × h

= 240 kg×9.8 ms-2×2.5 m

= 5880 J

Substituting the require values

= 1960 W
