37. an object is shot straight up from the ground with an initial velocity of 112 ft/sec.

a) find the interval of time t during which the object is 160 feet above the ground or higher.

b) at what time does the object reach its highest point and what is the highest point reached by
the object?
note: the equations relating to the motion of gravity are y = -16tº + vt + y, and
v=-32t + vo where v, is the initial velocity and y, is the height with respect to the ground at
time t = 0. here, we assume that y = 0 at the ground level.
