D
43

B. The ball will move with a constant speed.

Explanation:

Assuming a ball is traveling through space at a velocity of 25 m/s. The statement which best describes the motion of this moving ball if there is no external force applied to the ball is that, the ball will move with a constant speed in accordance with Newton's first law of motion.

Newton's first law of motion states that, an object or body will continue to be at rest or experience a uniform motion in a straight line at constant speed provided there's no action of an external force. Thus, unless compelled to change its state by an external force, a body will continue to be at rest or experience a uniform motion in a straight line.

The Newton's first law of motion is also known as the law of inertia; which is the tendency of a body to be at rest unless acted upon by an external force.

its c its is a mixture of gases

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be
