Unit 3 - Objective 2 Worksheet - Parametric Equations
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.
