Question

A projectile is launched with an initial velocity of 80 m/s at an angle of 30° above the horizontal. Neglecting air resistance, what is horizontal component of the projectile's acceleration? Select one: O a. 4.9 m/s^2 O b. O m/s^2 O c. 9.8 m/s^2 O d. 80 m/s^2 O e. 40 m/s^2

Answer 1

A projectile is launched with an initial velocity of 80 m/s at an angle of 30°

The vertical acceleration of the projectile is caused by gravity that is 9.8 m/s^2.

On the other hand, the horizontal component of the velocity remains constant throughout the flight.

A constant horizontal component of velocity means that the acceleration is zero.

Therefore, we can conclude that the horizontal component of the projectile's acceleration is 0 m/s^2

Option b is the correct answer.
