Conceptual Example 10 Two Ways to Throw a Stone From the top of a cliff, a person throws two stones. The stones have identical initial speeds, but stone 1 is thrown downward at some angle above the horizontal and stone 2 is thrown at the same angle below the horizontal. Neglecting air resistance, Sep 14, 2011 · From the top of a cliff overlooking a lake, a person throws two stones. The two stones have identical initial speeds of v0 = 13.7 m/s and are thrown at an angle θ = 28.0°, one below the horizontal and one above the horizontal.

A stone is thrown at an angle of 30 degrees above the horizontal from a building 45 meters high with an initial speed of 23 m/s. Find the minimum speed of the projectile during its flight. Let θ be the angle made by the resultant velocity with the horizontal component of velocity, 𝑣𝑣𝑥𝑥 ∴tanθ= 𝑣𝑣𝑦𝑦 𝑣𝑣𝑥𝑥 θ= tan−1 10 20 = tan−1(0.5) = 26.57o When the stone is dropped from the truck, the horizontal force acting on it becomes zero. and placed it in his own new tomb that he had cut into the rock. Then he rolled a great stone across the entrance to the tomb and went away. Matthew 27:66 So they went and secured the tomb by sealing the stone and posting the guard. Mark 16:4 But when they looked up, they saw that the stone had been rolled away, even though it was extremely large.
