A. If the ball that is thrown downward has an acceleration of magnitude a at the instant of its release (i.e., when there is no longer any force on the ball due to the woman's hand), what is the relationship between a and g, the magnitude of the acceleration of gravity?

a. a > g

__b. a = g__c. a < g

Doesn't the ball have a constant downward acceleration of 9.80 m/s^2?

B. Which ball has the greater acceleration at the instant of release?

a. the ball thrown upward

b. the ball thrown downward

__c. Neither; the accelerations of both balls are the same.__C. Which ball has the greater speed at the instant of release?

a. the ball thrown upward

b. the ball thrown downward

__c. Neither; the speeds are the same.__Both balls have the same givin initial speed v_0, so the speeds are the same?

D. Which ball has the greater average speed during the 1-s interval after release (assuming neither hits the ground during that time)?

a. the ball thrown upward

__b. the ball thrown downward__c. Neither; the average speeds of both balls are the same.

The ball thrown downward has a greater average speed because it speeds up due to gravity?

E. Which ball hits the ground with greater speed?

a. the ball thrown upward

b. the ball thrown downward

__c. Neither; the balls hit the ground with the same speed.__Don't both balls have a final velocity of 0 m/s if they hit the ground?

Thank you for any replies.
