A ball is thrown vertically upward with an initial velocity of 23.6 meters per second. What is the maximum height reached by the ball? Please include your answer with a unit symbol.

Answers

Answer 1
Answer:

Answer:

Maximum height attained by the ball will be h = 28.416 m

Explanation:

We have given initial speed of the ball u = 23.6 m /sec

At maximum height velocity will be zero so final velocity v = 0 m/sec

Acceleration due to gravity g=9.8m/sec^2

From law of motion we know that v^2=u^2-2gh

0^2=23.6^2-2* 9.8* h

h = 28.416 m

So maximum height attained by the ball will be h = 28.416 m

Answers

If an object is moving or at work, it is considered to be a particle with kinetic energy. In physics, kinetic energy is thought to be the energy of motion, it is an acquisition of energy of an object through the possession of motion. Other forms of kinetic energy are vibration, rotation, and translation.

Answer:

As a person pushes a box across a floor, the energy from the person’s moving arm is transferred to the box, and the box and floor become warm. During this process, energy is conserved.

B.varied.

C.unique.

D.surprising

Answers

The data must be reproducible: it means that the data will be reliable and representative and not that this data would lead to one conclusion and another data would lead to another.

Data being varied, unique or surprising does not have anything to do with acceptability of the conclusion.

A heavy brick weighs more than a fluffy cushion, but the cushion takes up more space. Which object has more matter? How do you know?

Answers

The heavy brick has more matter. The amount of matter in an object is determined by its mass, which is a measure of the total amount of material in the object.

Which object has more matter?

In this situation, the brick is heavier, which means it is bigger and has more stuff inside compared to the soft cushion.

Weight is the push or pull on something because of gravity, and it can change depending on how strong the gravitational field is. But, mass is a basic characteristic of stuff that stays the same no matter the pull of gravity. The brick is heavier, so it has more stuff inside than the cushion.
