Part B简答题部分

Solution to Problem 1：

1. The drag force due to air resistance on a falling object depends on the instantaneous velocity of the object as D = ­1/4 Av. Sketch a diagram of height vs. distance for the trajectory of two projectile objects launched from the same point at ground level with the same angle to the horizontal: a) – the projectile for which the air resistance is negligible, and b) ­the projectile that is experiencing a drag force in the air.

The drag will affect the x­and the y­component of the velocity of the projectile everywhere through its path. So, the lower height and the shorter horizontal distance are expected to be observed for an object that experiences the drag force due to the air resistance. The shape of the trajectory must change correspondingly.
