An object falls from rest. Its position at time t is given by s(t) = 1/2 gt^2. We consider that it falls for T seconds. (a) Write its velocity v as a function of time t and then write the velocity as a function of the position s. (b) Notice that v(T) denotes the nal velocity of the object. Write the average velocity v over the object during its fall, rst averaging over time t, and then averaging over position...

If an object is propelled upward from a height of s feet at an initial velocity of v feet per second, then its height h after t seconds is given by the equation h=−16t^2+vt+s, where h is in feet. If the object is propelled from a height of 1212 feet with an initial velocity of 9696 feet per second, its height h is given by the equation h =minus−16t^2+96 +12. After how many seconds is the height 120 feet?
