A ball is dropped from the top of a building. The ball takes $0.5$ s to fall past the $3$ m length of a window at certain distance from the top of the building. Time of travel above the window is (Take $g=10m/s^2$)

Q. A ball is dropped from the top of a building. The ball takes $0.5s$ to fall past the window of $3m$ in length at certain distance from the top of the building. ($g=10m/s^2$) How fast was the ball going as it passed the bottom of the window?

Q. A ball is dropped from the top of a building. The ball takes $0.5$ s to fall past the window $3$ m in length at certain distance from the top of the building. ($g=10m{s}^{-2}$)
Speed of the ball as it crosses the top edge of the window is

Q. A ball is dropped from the top of a building. The ball takes $0.5$ s to fall past the length of a window, the top of the window being at a distance of $3$ m from the top of the building. If the speed of the ball at the top and the bottom of the window are $V_T$ and $V_B$ respectively, then $(g=9.8m/se{c}^2)$

Q.

A ball is dropped from the top of a building. The ball takes 0.5sec to fall past the 3m height of a window some distance from the top of the building. If the speed of the ball at top and the bottom is vb and vt, the establish a relationship between vb and vt take (g = 9.8m/s).

Q.

A steel ball is dropped from a building's roof and passes a window of lenght $10\text{m}$, taking $1\text{s}$ to fall from the top of the window to the bottom of the window. It then falls onto a sidewalk and bounces back past the window, moving from bottom to top in $1\text{s}$. Assume that the upward flight is an exact reverse of the fall. The time the ball spends below the bottom of the window is $2\text{s}$. How tall is the building?
