Answer:
The ball was in the air for 5.0 seconds
Explanation:
When the ball is thrown above at a certain angle from the horizontal it follows a projectile motion.
The ball has a specific vertical and horizontal velocity.
The time take for the ball to reach at the top of its path is also the time taken by the vertical velocity vector to become zero. This is the first half of the projectile motion (ball is going up).
For the second half, the ball comes down and it accelerates with same gravitational acceleration from which it was decelerating in the first half. Hence the time to come down will be the same 2.5 seconds.
So the total time the ball was in the air is twice of 2.5, i.e,
5.0 seconds
Answer:
Inertia of an object depends on the <em>mass </em>of the object.
Explanation:
Inertia is the property that is possessed by a matter( anything that has weight and occupies space) that enables it to be at rest or in a state of continuous uniform motion.
<em>The inertial of a body is the resistance that is present in the body, that forces acting on the body have to overcome for the body to move or continue moving.</em><em> </em>
The inertia of a body depends on the mass of such a body, which is directly proportional. The mass of an object is the measure of inertia, the bigger the mass of an object the bigger the inertia.
<em>Therefore the Inertia of an object is largely dependent on the mass of such an object. </em>
