Question

A projectile is launched horizontally from a raised platform. If air resistance is ignored, then as the projectile falls to the earth, the magnitude of the vertical component of the velocity of the projectile:a. increases, while the horizontal component decreases.
b. increases, while the horizontal component remains constant.
c. decreases, while the horizontal component increases.
d. decreases, while the horizontal component remains constant.

Answer 1

The option ( b ) is appropriate answer

Explanation:

When a projectile is projected from height horizontally . The only force acting upon it is the downwards gravitational force of attraction due to earth .

Due to this force its vertical component of velocity , which is in the downward direction will be increased .

As there is no force horizontally , the horizontal  velocity of throw will remain constant .

Thus ( b ) option is the correct option .
