0.20\,\text{kg}

ball is projected vertically upward with a speed of

15\,\text{m/s}

. Neglect air resistance. Taking the upward direction as positive and

g = 9.8\,\text{m/s}^2

, calculate the net force acting on the ball

0.50\,\text{s}

after it leaves the hand. State the sign and direction of the force.
