- Problem 1: An object is launched off the top of a 45-m tall building with velocity of 70.9 m/s in the horizontal direction (no angle with respect to the horizontal). Pai. (a) In the space below, explain how you would find the time that the object is in the air. (Type the equation(s) you would use and the variable(s) you would solve for. Describe any other important steps. Do not show calculations or the numeric answer.)Find the following for path A in the figure below. (For each answer, enter a number.) A 0 (a) the distance traveled (in m) m t с D (c) the displacement (in m) from start to finish m B 24 68 8 10 12 displacement x (m) (b) the magnitude of the displacement (in m) from start to finish m iCalculate the height of a cliff if it takes 2.35 s for a rock to hit the ground when it is thrown straight up from the cliff with an initial velocity of 8.00 m/s. What is the maximum height reached by the rock? How long would it take to reach the ground if it is thrown straight down with the same initial speed? Clearly state the formulae you’re using and what your letters/symbols mean.
