Complete the following questions. Use the back of this sheet if you need more room. 1) The x and y coordinates of a moving particle are given by the parameteric equations: y=-t-7 Find the magnitude and direction of the velocity at time t=3 2) If the x and y coordinates of a moving particle as function of time are given by the parameteric equations: Find the magnitude and direction of (a) the velocity vector when time t=1 (b) the acceleration vector when t=1 3) A sphere is constrained to move along a parabolc path described by If the horizontal velocity is constant at 5.00cm/s, find the velocity when x=4.5.
