0.50\,\text{kg}

ball is launched straight upward from ground level with an initial speed of

12\,\text{m/s}

. During the ascent the ball experiences a constant

1.5\,\text{N}

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)

11\,\text{m}

(b)

3.2\,\text{m}

(c)

5.6\,\text{m}

(d)

7.3\,\text{m}
