Livia Graves · Answer 1

Given: Mass m = 250 Kg; Height h = 2.00 m; Time t = 2.00 s g = 9.8 m/s²

Required: Power output or P = ? Work = Force x distance W = F x d; F = mg

Formula: P = W/t P = Fd/t P = mgh/t

P = (250 Kg) (9.8 m/s²) (2.00 m) / 2.00 s)

P = 2, 450 Kg. m²/s³ or can also be written as

P = 2,450 J/s or Watts
