How far below an initial straight-line path will a projectile fall in one second

Physics
1 answer:
Anni [7]4 years ago
3 0

Answer:

9.8 m

Explanation:

The rate of free fall of a body does not depend on its mass or shape in the absence of air resistance.  This property of gravitational force is proved by the famous leaning tower of Pisa experiment by Galileo.

The gravitational force is responsible for the gravitational acceleration of a body.

When considering the gravitational acceleration near the surface of Earth it has the constant value g = 9.8 m/s irrespective of the mass of the body.

This phenomenon states that every projectile falls at the same rate such that its velocity keeps on increasing to maintain the constancy of g.

So, when a projectile fall initially from a certain height for one second, it would have traveled only 9.8 m.

Change the following data into scientific notation.<br><br> 5 000 000 km
RoseWind [281]
To find out scientific notation, you want to make sure that number is less than 10. So do 5.000000, you don't rally need the zeros but I just want to make my point. So use 10^x meaning ten the whatever power adds zeros like 5.000000x10^6 meaning it is increasing it by six zeros moving it out of the decimals and letting become 5,000,000.

Chameleon's tongue is more fast than thought. Its long sticky tongue moves at an amazing ballistic speed which lashes out unsuspecting insects and bugs. Now let us see how fast it is.

GIven:

acceleration of the chameleon's tongue- 260 m/s
2 for 20 ms
constant speed 30 ms
50 ms total time
1/20 of a second

solution:

<u>260</u> = <u>  n</u><u>  </u>
20       50
<u>20 n </u>= <u>13, 000</u>
20            20
n= 650 m/s

Which equation would you use to solve the following problem?
aivan3 [116]

The correct answer to the question is : C)The problem is asking to solve for work; W = F × d

EXPLANATION:

As per the question, the distance covered by the object d = 29 m.

The force that acts on the object is F = 289 N.

We are asked to choose the correct equation for work done.

Work is said to be done on a body or by a body if the applied force has a component along the direction of displacement.

Mathematically work done W = force × displacement

                                                  = F × d

As per the question, we are given distance covered and applied force.

Hence, the correct equation for calculating work done by the object is equation C.
