Question

a diver with a mass of 60 Kg is standing on the top of a 10 meter high platform. what is the mechanical energy

Answer 1

Answer:

M.E = 5880 J

Explanation:

Given data:

Mass = 60 Kg

Height = 10 m

Mechanical energy = ?

Solution:

Formula:

M.E = K.F + P.E

K.E = 1/2 × mv²

P.E = mgh

Diver is not moving so K.E will be zero.

M.E = mgh

M.E = 60 kg × 9.8 m/s² ×  10 m

M.E = 5880 J  ( j= kg m²/s²)
