a stone projected horizontally from the top of a tower with a speed of 4m/s lands on the level ground at a horizontal distance 25m from the foot of the tower. calculate the height[g=10m/s2].

Question

a stone projected horizontally from the top of a tower with a speed of 4m/s lands on the level ground at a horizontal distance 25m from the foot of the tower. calculate the height[g=10m/s2].
is it u squared divided by 2g

Damon · Accepted Answer

Horizontal problem: u = 4 forever d = 25 so t = d/u = 25/4 seconds in air vertical problem: h = (1/2)g t^2 h = (1/2)g (d/u)^2 = (1/2)(10)(625/16)

Henry · Answer

Dx = Xo*Tf = 25 m. 4m/s * Tf = 25. Tf = 6.25 s. = Fall time. h = 0.5g*Tf^2.
