A rocket is launched into the air. The projectile motion of the rocket can be modeled using h(t) = 112t –16t2, where t is the time since launch in seconds and h(t) is the height of the rocket at time t.

When will the rocket be 196 feet in the air?

after 2.0 seconds
after 3.5 seconds
after 4.5 seconds
after 7.0 seconds
