A projectile is thrown at an angle 30° from horizontal. Which statement about its vertical component of velocity is true?

1 answer:

3 0

Answer: A
There is constant downward acceleration due to the gravitational force exerted on the object due to the earth's gravitational field
By Newton's second law,
Force=Acceleration * Mass

Since vertical velocity is upward while vertical acceleration is downward, vertical velocity decreases as it moves upward.
