Question

Can someone please help with a free fall question. "You throw a stone vertically upward with an initial speed of 6.0 m/s from the 3rd story office window. if the window is 12 m from the ground fine the time the stone is in flight and the speed of the stone just before it hits the ground"

Answer 1

we can use the formula in kinetics to solve the problem expressed as x = vo + 1/2 gt2. vo as the initial velocity is equal to 6m/s and x is equal to 12 m. g is the acceleration due to gravity equal to 9.8 m/s2. Solving for t in the formula after substitution, t is equal to 1.1 seconds.
