BRAINLIESTTTT!!!
If Mary pitches a baseball with the initial height of 6 feet and a velocity of 73 feet per second, how long will it take for the ball to hit the ground? :)

Respuesta :

x = [ -73 +/- sqrt (73^2 - 4 * -16 *6) ] / (2 * -16)

73^2 - 4 * -16 * 6 = 5713

sqrt 5713= 75.58

(-73 - 75.58) / -32 = 4.64

Good luck :)

when the ball hits the ground H(t) =, 0 so just plug in 0 for H(t) , 6 for s and 73 for v, then solve for t.

 Hope this helps!
