For this problem, we will not be using the mass of the rock. .

The given values are as following : 1- Vo = 10.5 m/s. 2- the angle = 54 degree. 3- Vx = 15.3 4- Vy (the height of the building) = ? 5- ay = 9.8 m/s^2 6- ax = 0 m/s^2

We first use the equation (X-Xo) = (Vx)(cos Theta).t - (1/2).ax.t^2, to find the value of t, and since ax = 0 m/s^2, we get (X-Xo) = (Vx)(cos Theta).t. And then we get t.

After finding the value of t, we can use the equation (Y-Yo) = (Vy)(sin Theta).t - (1/2).ay.t^2 to find the value of (Y-Yo) which is the height of the building.
