Answer:
The ball would hit the floor approximately
after leaving the table.
The ball would travel approximately
horizontally after leaving the table.
(Assumption:
.)
Explanation:
Let
denote the change to the height of the ball. Let
denote the time (in seconds) it took for the ball to hit the floor after leaving the table. Let
denote the initial vertical velocity of this ball.
If the air resistance on this ball is indeed negligible:
.
The ball was initially travelling horizontally. In other words, before leaving the table, the vertical velocity of the ball was
.
The height of the table was
. Therefore, after hitting the floor, the ball would be
below where it was before leaving the table. Hence,
.
The equation becomes:
.
Solve for
:
.
In other words, it would take approximately
for the ball to hit the floor after leaving the table.
Since the air resistance on the ball is negligible, the horizontal velocity of this ball would be constant (at
) until the ball hits the floor.
The ball was in the air for approximately
and would have travelled approximately
horizontally during the flight.
Answer:
Motion is one of the important issues of Physics. We know that if we are not moving but still earth is moving. Motion is a bit of the machinist's Department of Physics. Several laws are provided for explaining the theory of motion and evolution in motion. The motion and transformation are defined in terms of strength which is wanted for creating an object in a motion state.
The distance is 20 miles
Explanation:
Definitions:
- Distance is the total length of the path covered by an object during its motion, regardless of the direction of its motion
- Displacement is the shortest distance between the initial and final position of the motion, so it also takes into account the direction of motion
In this problem, we want to know the distance covered by the woman. The motion consists of the following parts:
north
east
south
To find the distance, we just have to add the length of each path, ignoring the direction. Therefore:

The synonym for innovator and a NASA program for unmanned probes is Pioneer. Pioneer 10, launched in 1972. and Pioneer 11 launched in 1973. were the first probes that visited the outer planets and went beyond Pluto, Kuiper belt and into interstellar space. They both carry the gold-anodized aluminum plaque with naked human male and female and a map to Earth, designed by Carl Sagan, in case they are found by an extraterrestrial civilization outside the Solar system.
