Superman is supposed to leap tall buildings in a single bound. suppose that he obeys the normal laws of physics in this feat. estimate how fast he should be moving when he leaves the ground so that he just clears the top of disque hall. (hint # 1: how fast would he be moving if he just fell off the top? hint #2: you have to estimate how tall disque hall is.)

31.32 m/s

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration due to gravity = 9.81 m/s²

Let us assume the height of the Disque hall is 50 m

In order to make the jump Superman's initial velocity must be greater than or equal to 31.32 m/s

a) cold, dry

explanation:

continental polar masses are cold and dry air masses because the cold air cannot hold much moisture. as they move into warmer air, they can trigger precipitation.
