A 0.50kg ball is launched straight upward from ground level with an initial speed of 12m/s. During the ascent the ball experiences a constant 1.5N resistive force due to air. Neglect all other non-gravitational forces. How high above the launch point does the ball rise before momentarily coming to rest?
a) 11m
b) 3.2m
c) 5.6m
d) 7.3m
