To clarify the distinction between speed and velocity, and to review qualitatively one-dimensional kinematics.A woman stands at the edge of a cliff, holding one ball in each hand. At time t0 t_0 , she throws one ball straight up with speed v0 v_0 and the other straight down, also with speed v0 v_0 .For the following questions neglect air resistance. Pay particular attention to whether the answer involves "absolute" quantities that have only magnitude (e.g., speed) or quantities that can have either sign (e.g., velocity). Take upward to be the positive direction.Part A. If the ball that is thrown downward has an acceleration of magnitude a 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 a and g g, the magnitude of the acceleration of gravity?If the ball that is thrown downward has an acceleration of magnitude \texttip{a}{a}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 \texttip{a}{a}a and \texttip{g}{g}g, the magnitude of the acceleration of gravity?a>g a>ga=g a= gPart B. Which ball has the greater acceleration at the instant of release?Which ball has the greater acceleration at the instant of release?Part C. Which ball has the greater speed at the instant of release?Which ball has the greater speed at the instant of release?Part D. Which ball hits the ground with greater speed?Which ball hits the ground with greater speed?the ball thrown upwardthe ball thrown downwardNeither; the balls hit the ground with the same speed.

F(due to the woman’s hand) = 0 = m×a where m = mass and a = acceleration due to the woman’s hand then the only acceleration on the will be acceleration due to gravity g

a = g

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

Both balls have the same acceleration due to the force of the woman’s hand at the instant of release

C. Which ball has the greater speed at the instant of release?

Both balls have the same speed at release controlled by the movement of the woman's hand

D. Which ball hits the ground with greater speed?

Both balls hit the ground with the same speed as they both possess equal energy only the ball thrown upwards first converts its kinetic energy to potential energy before it gets converted back to kinetic energy on the way down
