a. Write parametric equations for the path of the ball.

I got this as x = 146.7cos(theta)t and y = 3 + 146.7sin(theta)t - 16t^2

b. Graph the path of the ball if theta = 15 degrees. Is it a home run?

I got no because the ball only reached 349 ft, not 400 ft.

c. Find the arc length of the path of the ball until it lands.

This is the part I need help on. I don't know how to get the arc length.
