Carla holds a ball 1.5 m above the ground. daniel, leaning out of a car window, also holds a ball 1.5 m above the ground. daniel drives past carla at 40 mph and, just as he passes her, both release their balls at the same instant. whose ball hits the ground first? explain.

Carla

Explination: As Daniel's ball is dropped from the car moving at 40 mph in a horizontal direction, at the time the ball is dropped it is also moving at 40 mph in a horizontal direction due to inertia, a property of mass causing resistance to change, Daniel's ball will continue to move in a horizontal direction even after being dropped along with falling due to gravity. Daniel's ball will then fall in a projectile motion curve of sorts which will cause an overall velocity to not be straight down causing it not to fall to the ground as quickly as Carla's ball.

Sorry for the long explanation

Carla

Explanation:

Thinking process:

First, we neglect the air resistance.

Carla is not moving. It means that the present energy of the ball is potential energy relative to its height from the ground. There is only a single velocity component on Carla's ball - the vertical component. Therefore, Carla's ball hits the ground first.

Daniel's case is different. The ball travels with two components of velocity - the horizontal velocity and the vertical component. Therefore, the ball's total velocity is a resolution of the two velocities.

Thus, the horizontal component of Daniel's ball follows a projector path and does not fall horizontally. It will touch the ground at some distance after being dropped to the ground.
