In Exercises 39 and 40, use the following information.
A shot put is thrown a distance of 54.5 feet at a high school track and field meet.
The shot put was released from a height of 6 feet and at an angle of 43°.
39. Write a set of parametric equations for the
path of the shot put.
Ans:
x = (v*cos43°)t, y = -16t^2 + (v*sin43°)t + 6 -or-
x = 0.731vt, y = -16t^2 + 0.682vt + 6
40. Use the equations to determine the speed
of the shot put at the time of release.
Must be solve without calc, but without t, how do you find v?
I solved the quadratic and found t in terms of v, plugged that into the x-EQ, but it became a quartic, it’s an Alg 2 class so there must be a simpler solution …
