A projectile is fired with an initial velocity of 230 feet per second at an angle of 45 degrees with the horizontal. The parametric equations describing its motions are
x = 115 - SQR(2)*t
y = 115- SQR(2)*t-16t².
Find the time when the projectile hits the ground, and the range of the projective (the horizontal distance covered).© BrainMass Inc. brainmass.com June 4, 2020, 3:01 am ad1c9bdddf
