Problema Solution

3) The path of a falling object is given by the function s = 16t^2 + v_0+s_0 where v_0 represents the initial velocity in ft/sec and s_0 represents the initial height in feet.

a) If a rock is thrown upward with an initial velocity of 64 feet per second from the top of a 25-foot building, write the height (s) equation using this information.

s = 16t^2 + v_0+s_0

a) If a rock is thrown upward with an initial velocity of 64 feet per second from the top of a 25-foot building, write the height (s) equation using this information.

Typing hint: Type t-squared as t^2

Answer:s = 16t^2 + 64ft/s + 25ft

b) How high is the rock after 1 second?

Answer:s = 16 x 1^2 + 64ft/s + 25ft

            S=105ft
