From the teacher's perspective, how does a piece of chalk appear to fall when dropped while walking at a speed of 1.5 m/s?
- A Straight down
- B Straight backward
- C Straight down and forward
- D Straight down and backward
That's Correct!
It's Wrong!
From the teacher's perspective, the chalk appears to fall straight down. This is because both the teacher and the chalk are moving forward at the same speed (1.5 m/s). When the chalk is released, it retains this horizontal motion. Since there is no relative horizontal movement between the teacher and the chalk, the only visible motion from the teacher's point of view is the vertical drop due to gravity. To an observer on the ground, the chalk would follow a parabolic path, but to the teacher, it seems to fall straight down.
