How long will it take an object to hit the ground if it is dropped from a hight of 176.4 meters ​

Physics

Oliga [24]3 years ago

There's a short handy formula for that.

If the object is just dropped and not tossed, and it's not affected by air resistance on the way down, then the distance it falls in T seconds is

D = (1/2) (gravity) (T²)

For this problem . . .

176.4 m = (1/2) (9.8 m/s²) (T²)

Divide each side by  (4.9 m/s²) :

T² = (176.4 m) / (4.9 m/s²)

T² = (36 s²)

Take the square root of each side:

<em>T = 6 seconds</em>

If a 2 kg object is falling at 3 m/s at what rate is gravity working on the object
777dan777 [17]

Answer:

+9.8m/s^2

Explanation:

The rate of gravity of the object is constant thriughout the surface of the earth.

For falling object, the rate of gravity is positive since the body is coming down (falling)

The rate of gravity is negative if the body is going up

The constant value for acceleration due to gravity is 9.8m.s^2

Since the object is falling, hence the acceleration due to gravity is positive.

Rate of gravity working on the object will be +9.8m/s^2

What are the horizontal and vertical components of a lizard’s displacement if it has climbed 7m directly up a tree?
madam [21]

Answer:

The horizontal component is zero.

The vertical component is 7\sin\theta

Explanation:

Given that,

The lizard climb 7m directly up on a tree.

We know that,

The horizontal component is

x=\cos\theta

The vertical component is

y=\sin\theta

If the lizard climb 7m directly up on a tree then,

We need to find the components

Using given data

The horizontal component of lizard is

x=0

The vertical component is

y=7\sin\theta

Hence, The horizontal component is zero.

The vertical component is 7\sin\theta

what is the main difference between a substance going through a physical change and one going through a chemical ?
Ainat [17]

Answer: Physical changes only change the appearance of a substance, not its chemical composition. Chemical changes cause a substance to change into an entirely substance with a new chemical formula. Chemical changes are also known as chemical reactions.
