I WILL MARK YOU AS BRAINLIEST IF RIGHT
You fall off the top of the Sears Tower and begin accelerating 9.8 m/s^2 toward the ground. If you fall for 10 seconds, how fast will you be going when you hit the ground ?

Respuesta :

Answer:

Falling from the Sears Tower

• After 5 seconds, the ball falling from the

Sears Tower will have fallen

distance = ½ • 32 ft/s2 • (5 s)2 = 16 • 25

= 400 feet.

• We can turn the formula around to figure

out how long it would take the ball to fall all

the way to the ground (1450 ft)

Ætime = square root of (2 x distance/g)

In theory you would be travelling with 10x9.8 = 98 m/s. In practice air resistance will be such that you will not accelerate to that speed. You would possibly reach terminal velocity after a few seconds, depending on your weight, size, and your body shape as you fall...
