Answer:

the range or the ball is 48.81 m

Explanation:

given;

Nicole throws a ball at 25 m/s at an angle of 60 degrees abound the horizontal.

find:

What is the range of the ball?

solution:

let Ф = 25°

Vo = 25 m/s

<u>consider x-motion using time of fight: x = Vox * t</u>

where x = R = range

t =<u> 2 Voy </u>

      g

R =<u> Vo² sin (2Ф)</u>

           g

plugin values into the formula:

R = <u>(25)² sin (2*25) </u>

               9.81

R = 48.81 m

therefore, the range or the ball is 48.81 m

Explain the term inertia<br>​
andreyandreev [35.5K]

Answer: See explanation

Explanation:

Inertia is the force that keeps an object at rest. Inertia is referred to as the property which results in it continuing in the state of rest that it is unless there's an external force that acts upon it.

Inertia keeps objects and things in place and it holds the universe together. When there's no force that's acting in an object, such object will continue to move in a straight line and also at a constant speed.
