Hi please answer and show your work​

Explanation:

Given:

Mass = m = 200,000 kg

Vertical Distance = h = 120 m

Speed = v = 14 m/s

Acceleration due to gravity = g = 10 m/s²

Required:

1) Gravitational Potential Energy = P.E = ?

2) Kinetic Energy = K.E. = ?

Formula:

1) P.E. = mgh

2) K.E. =

Solution:

1) P.E. = (200,000)(10)(120)

P.E. = 240,000,000 Joules

P.E. = 240 Mega Joules

P.E. = 240 MJ

2) K.E. = 1/2 (200000)(14)^2

K.E. = (100000)(196)

K.E. = 19,600,000 Joules

K.E. = 19.6 MJ

Hope this helped!

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.
