Answer #1

Solution:

First condiction, Distace nedd to be covered for 1 floor

d = 1/2gt2

2nd condiction,

d' = 1/2 g(2t)2

d' = 1/2 g *4t2

d' = 4*[1/2gt2] = 4d

Ans : A. 2nd story.

I hope you understood the problem, If yes rate me!! or else comment for a better solution

    Use the exact values you enter to make later calculations. A uniformly accelerated car passes three equally spaced traffic signs. The signs are separated by a distance d = 21 m. The car passes the first sign at t = 1.3 s, the second sign at t = 3.7 s, and the third sign at t = 5.5 s. (a) What is the magnitude of the average velocity of the car during the time that it is moving between the...

    A steel ball is dropped from a building's roof and passes a window, taking 0.210 s to fall from the top to the bottom of the window, a distance of 1.80 m. It falls to a sidewalk and bounces back pass the window, moving from bottom to top in 0.210 s. Assume that the upward flight is an exact reverse of the fall. The time the ball spends below the bottom of the window is 3.00s. a) How tall is...
