User blog:GreyFang82/Gourn stops an Allosaurus

In the Tomb of Annihilation campaign me and my friends are playing in, the barbarian in the group stops a charging Allosaurus with his bare hands. Also a Blood Hunter does the same thing but with a blood curse.

Now to see the lifting strength needed to do such a thing.

The Calculation
We will low-ball and use the [phttps://vsbattles.wikia.com/wiki/Allosaurus Allosaurus profile] in the main wiki for the info needed.

How I found out the way of calculating this feat is in this video

The Allosaurus weighs 1400 kg, and has an initial velocity of 8.3 meters per second in a distance of 5 feet. (This is because the check was considered a grapple check and that makes the movement of the allosaurus 0 instantly)

Initial Velocity = 8.3 m/s, Final Velocity is 0 m/s, Distance at which the dino reaches final velocity = 1.524 m (5 feet).

Acceleration of the Dino needs to be found.

Equation needed is -> Final Velocity ^ 2 = (Initial Velocity ^ 2) + (2 x Acceleration) x (The Change in Distance)

We want the final velocity to be zero so we plug that in...

0 = (Initial Velocity ^ 2) + (2 x (Acceleration)) x (The Change in Distance)

We subtract the initial velocity on both sides...

- (Initial Velocity ^ 2) = (2 x (Acceleration)) x (The Change in Distance)

Keep in mind we want the acceleration by itself so we divide both sides by 2 x (The Change in distance)....

- (Initial Velocity ^ 2) / 2 x (The Change in Distance) = Acceleration

Plug in the values and we get...

- (8.3) ^ 2 / 2 (1.52400) = -22.601706 m/s^2

Now the force needed to reduce the initial velocity to zero, is found with the equation...

Force = mass x acceleration

1400 x -22.601706 = -31642.3884 newtons, this is the negative force being acted on the allosauras in order to stop it, so we can make the value positive and we find the force Gourn put on the Allo to stop it. Which is 31642.3884 newtons or 3226.62 kg of force.

Conclusion
3226.62 kg of force is Class 5 lifting strength.

This scales to Gourn and Alex's Blood Curse of Binding.
