12. An object is launched at 19.6 meters per second from a 58.8 meter tall platform. The equation for the object's height s at time t seconds after launch is h(t) = -4.91² + 19.6t+ 58.8, where his in meters. When does the object strike the ground? a. t= -2 sec and t = 6 b. t=0 sec c. t = 2 sec d. t = 6 sec
