backward movement

because momentum = mass × speed

And mass must be in positive value..

so negative value is speed

which moving backward..

How does gravity and density affect weight
frozen [14]
<span> </span>

Gravity affects weight because gravity creates weight. Objects have mass, which is defined as how much matter an object contains. Weight is defined as the pull of gravity on mass.

<span> The relation between weight and gravitational pull is such that, when on another celestial body, the difference in gravity would alter a person's weight. The Earth's moon, for example, has a gravitational field that is 0.165 times the pull on earth. A person who weighs 170 pounds on Earth would only weigh 28.05 pounds on the moon. This is why during the moon landing videos, people on earth viewed the astronauts taking large, bounding steps. With very little weight, it was easy for them to push off the ground.</span>

Why do you think scientists put their results in data tables and graphs?
Nikolay [14]

Answer:Since most of the data scientist collect is quantitative, data tables and charts are usually used to organize the information • Graphs are created from data tables • They allow the investigator to get a visual image of the observations, which simplifies interpretation and drawing

Have a nice day (^-^) ;)

Calculate the hang time of a person who moves 3 m horizontally during a 1.25-m high jump. What is the hang time when the person
jekas [21]

The duration of time for which an object stays in air is called the hang time.

For an athlete who moves 3m horizontally during a 1.25m high jump, the hang time will be the sum of the time taken by the athlete to reach the maximum height and the time taken for the athlete to reach the ground from maximum height.

Calculate the time taken t_1 by the athlete to reach the maximum height

t_1 = \sqrt{\frac{2h}{g}}

t_1 = \sqrt{\frac{2(1.25)}{9.8}}

t_1 = 0.5s

The athlete takes same time to reach the ground from the maximum height, so t_2 = 0.5s

Calculate the hang time will be

t =t_1+t_2

t = 0.5+0.5

t = 1s

Therefore the hang time of the athlete when he moves a horizontal distance of 3m is 1s.

Similarly, when the athlete runs 6m horizontally, then also there will not be a change in the hang time of the athlete as the hang time is independent of the horizontal distance covered.
