After t seconds, a projectile hurled with initial velocity vo and angle 0 from an initial height of ho will be at I(t) = (vo cos(0))t feet and y(t) = (vo sin(0))t - 16t2 + ho feet. (This formula neglects air resistance.) initial speed = v 0 = initial angle For an initial velocity of 113 feet per second at an angle of 78" and an initial height of 1 feet, a) Find the horizontal distance an object has traveled when the object is at its highest point. (You might want to double check that your calculator is in degree mode!). feet. b) Find the horizontal speed when the object is at its highest point. The horizontal speed when the object is at a maximum height = feet per second. BE SURE TO UPLOAD WORK Edit * Insert Formats .
