Math 1920 Worksheet 2 1) The position and velocity curves of the problem just discussed are plotted below. The velocity curve has some asterisks that denote specific t values. Approximate where the corresponding position asterisks should be for each t value. -6 -4 -2 0 2 4 6 8 -8 -6 -4 -2 0 2 4 x y t = [0 , 2pi] Position Velocity 2) A particle moves along an ellipse 1 2 3 2 2 = + z y in the yz –plane in such a way that the position vector is given as follows: r = t cos 3
