I need help with questions a,b,c,d please!

Consider the following descriptions of the vertical motion of an object subject only to the acceleration due to gravity. (Note: the acceleration due to gravity is 9.8 m / s. ) a. Find the velocity of the object for all relevant times. b. Find the position of the object for all relevant times. c. Find the time when the object reaches its highest point (What is the height?) d. Find the time when the object strikes the ground. A payload is released at an elevation of 500 m from a hot-air balloon that is rising at a rate of 14 m / s. a. v(t) = b. s(t) = c. The object's highest point is |m at time t= |s (Simplify your answers. Round to two decimal places as needed.) d. t = (Simplify your answer. Round to two decimal places as needed.) Enter. your answer in each of the answer boxes. Take a Test - Ivan Sierra
