A projectile is fired with initial velocity vo at an angle θ0 with the horizontal and follows the trajectory shown above. Which of the following pairs of graphs best represents the vertical components of the velocity and acceleration, v and a, respectively, of the projectile as functions of time t?
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?
vP < vQ < vR
vR < vQ < vP
vQ < vR < vP
vQ < vR = vP
vP = vQ < vR
