Asked by bob
If you toss a ball straight up while in a closed train car and the ball hits the front of the car, then the train car could be
a) moving backward at constant speed
b) moving forward and slowing down
c) moving forward and speeding up
d) all of these are possible
e) none of these is possible
If it's hitting the front of the car, wouldn't the car have to be moving forward and slowing down? Because they're two opposite forces and opposing each other?
