A rock climber climbs a 15 m vertical rock wall while wearing a 5.3 kg backpack. How much work does the climber do on the backpack?

  • physics - ,

    Work = Potential Energy increase = M g H

  • physics - ,

    d = 15 m
    w = 5.3 kg
    g = 10 m/s²
    W = ?
    F = mg
    F = 5.3 kg x 10 m/s²
    F = 53 N
    W = F x d
    W = 53 N x 15 m
    W = 795 Joules
