Use the model for projectile motion, assuming there is no air resistance and g = 32 feet per second per second.
The path of a ball is given by the following rectangular equation.
y = x − 0.005x2
Use y = −((4.9/v02)(sec\theta)2)x2+tan(\theta)x+h to find the position function r(t) and the direction v(t).
Find the direction, v(t), and speed, v(t), of the ball at the point at which it has traveled 70 feet horizontally. (Round v(t) to one decimal place.)
v(t)=
v(t)= units are in ft/sec
