The 9mm Glock bullet travels at approximately v = 366 m/s. For a falling object starting from rest, its height above the ground is given by
h = -1/2 * g * t^2.
Solving for time:
t = sqrt(-2h/g).
If the bullet is fired level from a height of h = 2 m, then:
t = sqrt[-2 * 2m / (-9.81 m/s^2)] = 0.64 s.
The bullet would cover a horizontal distance of:
x = v * t = 366 m/s * 0.64 s = 234 m.
Thus, the contestants need to cover the initial d = 334 m (234 m + 100 m) in under 0.64 s.
To find the minimum required average acceleration, we use:
d = 1/2 * a * t^2.
Solving for a:
a = 2d / t^2 = 2 * 334 m / (0.64 s)^2 = 1,631 m/s^2.
Therefore, they need a minimum acceleration of 1,631 m/s^2.
Surfer is the only one with that level of acceleration, unless Thor, Hulk, and Thanos are able to push off a very durable vertical wall at the start of the bullet firing.
Note: If we account for air resistance, the bullet only travels approximately 162m before falling. In that case, the contestants would need a minimum acceleration of 1279m/s^2.
