Size:  485.8 KBWe haven't actually been taught any of mechanics yet so there is a reason I don't know how to do this but we have been given the textbook and when I flicked through the textbook, this first question really confused me. Out of curiosity, how do you do this with only 1 value?

    You know 3 values
    Starting velocity = 0 (it starts from rest)
    Acceleration = 9.8 m/s^2 (Gravity)
    Displacement = 40 m

    Your text book will explain the kinematics formulae you can then use (SUVAT)

    You actually know 3 values, the 40, "rest" means the iitial velocity was zero, and the acceleration due to gravity is 9.8 ms^(-2) downwards.

    Now all you need to know is some formulae.
