Answer:
[tex]\huge\boxed{\sf P.E. = 240\ MJ}[/tex]
[tex]\huge\boxed{\sf K.E. = 19.6\ MJ}[/tex]
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. = [tex]\displaystyle \frac{1}{2} mv^2[/tex]
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
