A 0.5 kg ball is thrown vertically upward at a speed of 25 m/s. Its velocity, v(t) (in m/s), at time, t (in seconds), is given by v(t)= 25-9.8t

Its kinetic energy, K(v) (in Joules), is given by K(v)=0.5v^2.
Express the ball's kinetic energy as a function of time, K(t).

  1. 2.) Write the equation of the circle in the standard form. Find the center, radius, intercepts & graph the circle.

    X^2 + y^2 + 16x -18y +145=25 = (x + 6)^2 + (y-7)^2 =25 = standard form
