Questlon: Your younger brother is playing with slingshot and trylng to shoot a rock straight up at 30 m/s from the top of dam. You noticed that the rock strikes the water 325 m below the starting point. You are thinking about the motion of the rock and trying to calculate some information. Assuming launching point is your reference, (1) Calculate how high does the rock rise? and how long it will be in air before strikes the water. How long would it have been in air if it had been launched straight down with same initlal speed? And how long if dropped from rest? (iii) Sketch the graph of position and velocity as a function of time for each of the three case. (launching upward, downward and from rest) (ii)
