PHY205 Ch2: 2D KinematicsYou are a vet trying to shoot a tranquilizer dart into a monkey hanging from a branch in a distant tree. You know that the monkey is very nervous, and will let go of the branch and start to fall as soon as your gun goes off. In order to hit the monkey with the dart, where should you point the gun before shooting?
A) Right at the monkeyB) Below the monkeyC) Above the monkey

A flatbed railroad car is moving along a track at constant velocity. A passenger at the center of the car throws a ball straight up. Neglecting air resistance, where will the ball land?
A) Forward of the center of the carB) At the center of the carC) Backward of the center of the car
