    Letting V = the velocity at first contact, we can write: (2) M g H = .5 M V^2 Your canceling M and solving for V by substituting the knowns g and H should give you the velocity V= 5.94 m/sec. c.

  • Rate of change and the chain rule

    Alternatively, one can write R in terms of t, by replacing the expression for x: R=1/(12t+2)^2 Then dR/dt=-24/(12t+2)^3, so dR/dt=-3 implies that -24/(12t+2)^3=-3, or equivalently (12t+2)^3=8. Solving for t gives only one value, t=0.
