Question

A stone is thrown from the top of a building upward at an angle of 30* to the horizontal and with an initial speed of 20 m/s, as in the Figure. Ifthe height of the building is 45 m, (a) how long is the stone "in flight"? (b) What is the speed of the stone just before it strikes the ground? Vo = 20 m/s 45 m

Step 1

The initial vertical velocity (Voy) can be found using the equation Voy = Vo*sin(θ), where Vo is the initial speed and θ is the angle. Substituting the given values, we get Voy = 20*sin(30) = 10 m/s. The initial horizontal velocity (Vox) can be found using the Show more…
