The elevations of the ski jumping hill shown below are as follows: hA = 37 m hB = 2.4 m hC = 5.5 m If the velocity of a ski jumper is measured to be 25.3 m/s at position B, what will be the launch velocity (in m/s) at position C [round your final answer to one decimal place]?

please answer a to g for student 3. thanks

Q1. 1) The missile at point A takes off from rest and rises vertically to point B after 6.7 seconds, where its fuel runs out. During this time the acceleration of the missile is a = (C.t) m/s², where C = 3.4 is a constant and tis time in s. (Hint, this expression of acceleration already takes into consideration of gravity.) Then by internal controls the missile tilts to an angle = 40° as shown, while keeping the speed, vg, it has attained, and from there it travels in free flight until it lands on the ground at point D. Determine the missile's height he (in m) at point B. Your answer must include 1 place after the decimal point. Take g = 9.81 m/s². C B hB hc R- D

I need these three parts answered, if you are unable to answer all three parts please leave it for another tutor to answer, thank you.
