Question

A projectile is launched with an initial velocity of 80 m/s at an angle of 30 degree above the horizontal. Neglecting air resistance, what is horizontal component of the projectile's acceleration?

a. 80 m/s²
b. 40 m/s²
c. 9.8 m/s²
d. 0 m/s²
e. 4.9 m/s^2

Answer 1

The horizontal component of a projectile's acceleration is d)0 m/s².

Step-by-step explanation:

The horizontal component of a projectile's acceleration is d)0 m/s².

The horizontal component of velocity remains constant throughout the entire motion as there is no horizontal force acting on the projectile. Therefore, there is no acceleration in the horizontal direction.

Only the vertical component of the acceleration is affected by gravity.
