Question

How does the vertical acceleration at point a compare to the vertical acceleration at point c?

Answer 1

Both accelerations are equal to free-fall acceleration.

Further explanation

• This is a matter of projectile motion, i.e., an object moving in two dimensions. The shaped is called a parabola.
• The only forces acting during its flight are gravity and friction. In many situations, air resistance can be ignored.
• It is moving horizontally and vertically at the same time but recalls this, the horizontal dan vertical components of the motion are independent of one another. Assuming the gravitational force is constant.

Horizontal component

There are no forces in the horizontal direction, so there is no horizontal acceleration, i.e., a = 0 m/s². This means the horizontal velocity must be constant along the track.

Vertical component

There is naturally a constant vertical force acting down, so there is a constant vertical acceleration. The value of vertical acceleration is similar to gravity (g).

See the attachment for the motion diagram.

Therefore the vertical acceleration at point A and point B is the same as free-fall acceleration.

Answer 2

The vertical accelerations of the point a and point c are equal. because the vertical acceleration is due to the acceleration due to gravity. Acceleration due to gravity may refer to: Gravitational acceleration, the acceleration caused by the gravitational attraction of massive bodies in general, which is equal to 9.8 m/s^2
