A reaction that releases energy as it occurs is classified as a(n ________.
cluponka [151]
The reaction that releases energy is called an EXOTHERMIC process. This is a word from the prefix exo- which means to exit and from the root word therm which is a unit of heat which in turn is form of energy. This is the opposite process of ENDOTHERMIC process.

What is Newton's Law
r-ruslan [8.4K]
I hope you are referring to Newton's Laws of Motion by "Newton's Law".

There are three laws quoted by the great physicist of all time Sir Isaac Newton.

These laws are the building-blocks of the field of the Physics known as Classical Physics or Classical Mechanics.

Law 1. If no force applied externally, then a body in rest will always be in rest and a body in motion will continue to move in a straight line with a uniform velocity.

Law 2. The rate of change of momentum is directly proportional to the force applied and the direction of motion is always in the direction of the force applied.

Law 3. Every action has an equal and opposite reaction.

The Law 1 is also called the law of Inertia.

From the 2nd law, we can derive the equation of force, that is F =m.a (m = mass; a = acceleration)

To win the game, a place kicker must kick a
masya89 [10]

Answer:

0.57 m

Explanation:

First of all, we need to calculate the time it takes for the ball to cover the horizontal distance between the starting position and the crossbar. This can be done by analzying the horizontal motion only. In fact, the horizontal velocity is constant and it is

v_x = u cos \theta = (15)(cos 51.7^{\circ})=9.30 m/s

And the distance to cover is

d = 19 m

So the time taken is

t=\frac{d}{v_x}=\frac{19}{9.30}=2.04 s

Now we want to find how high the ball is at that time. The initial vertical velocity is

u_y = u sin \theta = (15)(sin 51.7^{\circ})=11.77 m/s

So the vertical position of the ball at time t is

y(t) = u_y t - \frac{1}{2}gt^2

where g = 9.8 m/s^2 is the acceleration of gravity. Substituting t = 2.04 s, we find

y=(11.77)(2.04)-\frac{1}{2}(9.8)(2.04)^2=3.62 m

The crossbar height is 3.05 m, so the difference is

\Delta h = 3.62 - 3.05 =0.57 m

So the ball passes 0.57 m above the crossbar.
