Question

a student throws a baseball upwards at an angle of 60 degrees to the horizontal. the initial horizontal and vertical components are 12.5 m/s and 21.7 m/s, respectively. according to the information and diagram shown above, what position will have the greatest magnitude of vertical acceleration? a c b the magnitude of acceleration is the same at all the positions.

Explanation:

Step1: Identify the acceleration acting on the ball

The only force acting on the baseball in - air (neglecting air - resistance) is the gravitational force. The acceleration due to gravity \(g\approx9.8\ m/s^{2}\) acts vertically downwards throughout the motion of the projectile.

Step2: Analyze acceleration at different positions

At any point A, B, or C during the projectile motion of the baseball, the vertical acceleration is equal to the acceleration due to gravity. The acceleration due to gravity is a constant near the surface of the Earth and is not affected by the position of the projectile in its trajectory.

Answer:

The magnitude of acceleration is the same at all the positions.
