A ball is thrown and follows the parabolic path shown above. Air friction is negligible. Point $Q$ is the highest

point on the path. Points $P$ and $R$ are the same height above the ground.

How do the speeds of the ball at the three points compare?

$($A$)v_Q$

Which $of$ the following diagrams best shows the direction $of$ the acceleration $of$ the ball $at$ point $P?v_Q$

$(D)v_Q$

Which $of$ the following diagrams best shows the direction $of$ the acceleration $of$ the ball $at$ point $P?v_R$

$(C)v_Q$

$(D)v_Q$

Which $of$ the following diagrams best shows the direction $of$ the acceleration $of$ the ball $at$ point $P?v_P$

$(B)v_R$

$(C)v_Q$

$(D)v_Q$

Which $of$ the following diagrams best shows the direction $of$ the acceleration $of$ the ball $at$ point $P?$
