Question

current attempt in progress each drawing shows three points along the path of a projectile, one on its way up, one at the top, and one on its way down. the launch point is on the left in each drawing. which drawing correctly represents the acceleration a of the projectile at these three points? a = 0 m/s² a = 0 m/s² a = 0 m/s² 1 2 3 4 5 o 4 o 5 o 3 o 2 o 1

Explanation:

Step1: Recall projectile - motion acceleration

In projectile motion, neglecting air - resistance, the acceleration is due to gravity. The acceleration due to gravity $g$ acts vertically downwards throughout the motion of the projectile.

Step2: Analyze acceleration at different points

At the highest point of the projectile's path, the vertical component of velocity is zero, but the acceleration is still $g$ (downwards). At points on the way up and on the way down, the acceleration remains $g$ (downwards) as well. There is no horizontal acceleration (neglecting air - resistance).
