An object is launched vertically in the air at 31.85 meters per second from a 4​-meter-tall platform. Using the projectile motion model h(t)=−4.9t2+v0t+h0, where​ h(t) is the height of the projectile t seconds after its​ departure, v0 is the initial velocity in meters per​ second, and h0 is the initial height in​ meters, determine how long it will take for the object to reach its maximum height. What is the maximum​ height? The object will reach its maximum height in how many seconds. what is the maximum height obtained by the ball
