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 $3$ m length of a window at certain distance from the top of the building.
($g=10m/s^2$)
How far is the top of the window from the point at which the ball was dropped ?

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 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 $100m$ high. At the same instant another ball is thrown upwards with a velocity of $40m{s}^{-1}$ from the bottom of the building. The two balls will meet after.
