Projectile MotionA projectile is launched at an angle of 45°ï¿½ with the horizontal and with an initial velocity of 64 feet per second. A television camera is located in the plane of the path of the projectile 50 feet behind the launch site (see figure).
(a) Find parametric equations for the path of the projectile in terms of the parameter
(b) Write the angle αa that the camera makes with the horizontal in terms of
(c) Use the results of part (b) to find
(d) Use a graphing utility to graph
(e) At what time is the angle

- Object A is travelling along a circle of radius 2, and Object B is travelling along a circle of radius 5. The object have the same angular speed. Do the objects have the same linear speed? If not, which object has the greater linear speed?arrow_forwardWhat is parametric equation?arrow_forwardDetermine the parametric and symmetric equations for the line through the given points (2, –7,5), (-4, 2,5)arrow_forward
- A wheel with radius 2 cm is being pushed up a ramp at a rate of 7 cm per second. The ramp is 790 cm long, and 250 cm tall at the end. A point P is marked on the circle as shown (picture is not to scale). P 790 cm 250 cm Write parametric equations for the position of the point P as a function of t, time in seconds after the ball starts rolling up the ramp. Both x and y are measured in centimeters. I = y = You will have a radical expression for part of the horizontal component. It's best to use the exact radical expression even though the answer that WAMAP shows will have a decimal approximation.arrow_forwardExplain how you would graph the following set of parametric equations by plotting points and describing the orientation x=3t and y=t^2arrow_forwardYou're going for a bike ride and start 7km north of the town and riding on a straight path that leads to a park 3km west of town. It takes 20 minutes to cover this distance. Write parametric equations expressing your motion, with the town being represented by the origin, and t=0 representing your starting point then find your location after 5 minutes using these parametric equations. Then eliminate the parameter to get a rectangular equation for this path and verify algabraically that this equation represents this line and that both the parametric and rectangular equations are the same. Suppose you ride back along the same path, but now t=0 represents the new starting point, which was the original ending point. Explain what changed in the parametrization and if the rectangular equation changed.arrow_forward
