User blog:GreyFang82/World of Tomorrow: Sakura yeets a forking boulder

Alright, so before we can get into the actual calculations we have to figure out and estimate a few things before hand.

Here's the things we do know: -The Boulder weighs 1200 pounds (544.3108 kilograms) -The Boulder was thrown a fair distance -The Boulder was thrown too fast for athlete level characters to react

What we need to figure out: -The Distance -The Speed of the Boulder

Estimating What We Need
Alright, so we will try out three different distances

3.5 meters (~11.5 feet) for the low-ball

5 meters (16.4 feet) for the mid-ball

7 meters (~23 feet) for the high-ball

Now, in all these distances the boulder had to hit the opponents before they could react, so buy using the "Reactions" table for time frames we will assume that the boulder hit them after 0.128 seconds (Just barely above baseline athlete perception).

Low-ball 3.5 meters / 0.128 seconds = 27.34375 m/s

Mid-ball 5 meters / 0.128 seconds = 39.0625 m/s

High-Ball 7 meters / 0.128 seconds = 54.6875 m/s

The Actual Calculation
Now that we have the things we need we can find both the strength needed to throw the boulder as fast as Sakura did, and how much energy it produced.

The Force
The Formula is Force = Mass x Acceleration

Low-Ball 544.3108 x 27.34375^2 => 544.3108 x 747.680664063 = 406970.660401 newtons => 41499.45806180774 kg of force which is Class 50 Lifting Strength

Mid-Ball 544.3108 x 39.0625^2 => 544.3108 x 1525.87890625 = 830552.368164 newtons => 84692.77155457648 kg of force which is Class 100 Lifting Strength

High-Ball 544.3108 x 54.6875^2 => 544.3108 x 2990.72265625 = 830552.368164 newtons => 1627882.6416 kg of force which is Class M Lifting Strength

The Energy
Now we do the kinetic energy

The formula is K.E. = 1/2 Mass x Velocity ^ 2

Mass of the boulder: 544.3108 kg / 2 = 272.1554

Low-Ball 272.1554 x 27.34375^2 => 272.1554 x 747.680664063 = 203,485.3302 joules (Wall Level)

Mid-Ball 272.1554 x 39.0625^2 => 272.1554 x 1525.87890625 = 415,276.184082 joules (Wall Level)

High-Ball 272.1554 x 54.6875^2 => 272.1554 x 2990.72265625 = 813,941.320801 joules (Wall Level)

Lifting Strength
Low-Ball => Class 50 (41499.45806180774 kg of force)

Mid-Ball => Class 100 (84692.77155457648 kg of force)

High-Ball => Class M (1627882.6416 kg of force)

Kinetic Energy
Low-Ball => 203,485.3302 joules (Wall Level)

Mid-Ball => 415,276.184082 joules (Wall Level)

High-Ball => 813,941.320801 joules (Wall Level)
