vo 1 2 3 4 0 of 5 Where does the projectile end up? Moving Earth A cart is moving at constant velocity (constant speed in a straight line). A projectile is fired straight up from the cart. • At the original position of the cart • Ahead of the original position, but behind the cart • Back in the cart • Ahead of the cart • Not enough information Your Prediction: Your Observation:
Vo = 0 Vo 2 1 0 of 5 Which ball hits the ground first? Acceleration of Gravity - IV Two balls are released at the same time. Ball 1 is released from rest and ball 2 is given an initial horizontal velocity. The dashed line shows the ball’s trajectory. • Ball 1 • Ball 2 • Both hit at the same time • Not enough information Your Prediction: Your Observation:
1 2 3 4 0 of 5 Where does the projectile end up? Monkey & Hunter A monkey is hanging from a branch of a tree. A hunter aims directly at the monkey. In an attempt to avoid being shot, the monkey lets go of the branch the instant the projectile leaves the gun. • At the original position of the monkey • Below the original position, but over the monkey’s head • It hits the monkey • Below the monkey • Not enough information Your Prediction: Your Observation:
0 of 5 When the ball reaches its highest point, which is true: Projectile Motion - I • Zero zero • Non-zero zero • Zero non-zero • Non-zero non-zero You throw a ball straight up into the air. Your Prediction: VelocityAcceleration
Projectile #1 Projectile #2 0 of 5 If the shells follow the paths shown, which hits the ground first? Projectile Motion - II Two projectiles are fired simultaneously from the same location. • Projectile #1 • Projectile #2 • Both hit at the same time • Need more information Your Prediction: Your Observation:
