An object in projectile motion will follow wich path

Answers

Answer 1

Answer: It will tend to follow a trajectory path. When a projectile is being flung or flown away by a certain type of force, the trajectory is what it follows through the means of both force and function of time itself. It's also called as flight path.

The equation h=80t-16t^2 models the height h in feet reached in t seconds by an object propelled straight up from the ground at a speed of 80 ft/s. use the discriminant to find whether the object will ever reach a height of 90 ft

Answers

The object will reach a height of 90ft

To solve this exercise we are going to use the discriminant of the quadratic polynomial ax²+bx+c=0, which is b²-4ac.

If the discriminant is negative, then there are no real solutions to the equation.

If the discriminant is zero, there is only one solution.

If the discriminant is positive, there are two real solutions.

We have the equation h(t)=18t-16t² which describes the model of the height h (feet) reached in t (seconds) by an object propelled straight up from the ground at a speed of 80 ft/s. We want to use the discriminant to find whether the object will ever reach a height of 90ft.

First, we have to rewrite the equation to the form ax²+bx+c=0 and we know the height that is possible to reach for the object h=90ft.

90 = 80t-16t² ----------> -16t²+80t-90=0

Using the discriminan equation D = b²- 4ac.

From the quadratic polynomial -16t²+80t-90=0, we have a = -16, b = 80, and c = -90

D = (80)² - 4 (-16)(-90)

D = 6400 - 5760 = 640

Since the discriminant D is positive, the object will reach a height of 90ft.

A clown hangs two balloons from either end of a hanger. The air from on balloon is released, and the hanger tilts. Which principle is illustrated? a. gas is matter, and therefore has mass b. gas has volume that is not measurable c. released gas has a higher temperature than inert gas d. matter may never be destroyed

Answers

Answer:

A.) gas is matter, and therefore has mass

Explanation:

The principle illustrated in this scenario is a. gas is matter, and therefore has mass.

When the air from one balloon is released, it creates a flow of gas in one direction. According to the principle of gas having mass, the released gas exerts a force on the hanger, causing it to tilt. This demonstrates that gas is matter and has mass.

It's important to note that gas does have volume, which can be measured. This is not the principle being illustrated in this scenario.

The principle of released gas having a higher temperature than inert gas is not applicable in this scenario, as no information is given about the temperatures of the gases involved.

The principle of matter may never be destroyed is a general principle in physics and does not specifically apply to this scenario.

How would I calculate the X from a known velocity when launching a ball off a table?

Answers

Here are the steps you would need to follow:

#1). Define what 'the 'X is, and how it's related to the ball.
#2). Be clear on how 'the X' is related to the 'known velocity'.
#3). Identify how the 'known velocity' is related to the action of the ball when it's launched.

With this information in front of you, you'll have a much better chance
of answering the question.

With none of it in front of me, I have no chance at all.

Use the equation:

$X=ut+ (1)/(2) at^(2)$
where u is the initial velocity, a is the acceleration downwards (in this case $a=g=9.81m s^(-2)$ )

Hope this helps :)
