Homework Statement
A young child standing in the aisle of a parked bus tosses a ball straight up in the air and let's it drop at her feet. If instead the bus is moving at a constant speed of 30 km/h straight down the street and the child tosses the ball up in the air and let's it drop, where will the ball land? Why?
Would the result be the same if the bus were accelerating when the ball was tossed? If the child started running down the aisle of the bus after tossing the ball? If the bus made a turn to the left while the ball was tossed? Why or why not?
Homework Equations
I don't think there are any... it's not a math-based physics course.
The Attempt at a Solution
Part one:
The ball will still land by her feet, since she, the ball and the bus are all moving at a constant 30 km/h, and the horizontal component of motion for a projectile is completely independent of the vertical component of motion.
Part two:
The results would be the same; the ball would land in the same place. The ball is still moving at the same speed as the bus, and is unaffected by the motion of the bus.
Is this a correct answer? Thanks so much for your help!
