A Ball of Relatively Low Density Is Thrown Upwards

Multiple Choice

A ball of relatively low density is thrown upwards.Because of air resistance the acceleration while traveling upwards is −10.8 m/s².On its trip downward the resistance is in the opposite direction,and the resulting acceleration is −8.8 m/s².When the ball reaches the level from which it was thrown,how does its speed compare to that with which it was thrown?

A) It is greater than the original speed upward.
B) It is the same as the original speed upward.
C) It is less than the original speed upward.
D) Without knowing the original speed,this problem cannot be solved.
