A heavy piece of machinery is raised by sliding it a distance d equals 12.5 m along a plank oriented at angle 20 degrees to the horizontal. How far is it moved A. vertically and B. horizontally?

A). Vertical displacement = 12.5 sin(20) = 4.275 meters (rounded)
B). Horizontal displacement = 12.5 cos(20) = 11.746 meters (rounded)

Is both the work done are same when you travel the same distance along horizontally and vertically?
No, unless both are zero. No work is done in a horizontal motion. mGh is work in a vertical direction.
How can a ball be thrown that it reaches the longest distance across vertically horizontally angled?
if the bal is thrown by making 45 degree angles. with the ground..it will travel maximum distance...
How does one calculate the space to mounting height ratio for lighting?
Half the distance from the wall to the centre of the luminaire, as the distance there is between luminaires. e.g if the distance between luminaires horizontally is 3m then the distance to the centre of the luminaire from the wall is 1.5m. If the distance between the luminaires vertically is 5m then the distance to the centre of the luminaire from the wall is 2.5m
What is the taxi distance between the points 0-0 and 5-2?
The taxi distance, also known as the Manhattan distance, between the points (0,0) and (5,2) would be 5 units horizontally and 2 units vertically. Therefore, the taxi distance is 7 units.
What is the horizontal distance between called?
It is called the displacement in the horizontal direction.
What is the furthest distance an object has been thrown by a human vertically and horizontally?
Horizontally

What are the 3 important things to remember when using latitude and longitude?
1.longitude lines go vertically 2. latitude lines go horizontally 3.latitude is the angular distance o degrees of the equator By "vertically" is meant "north-south". By "horizontally" is meant "east - west".
What do you need to know to be able to determine how far a projectile travels horizontally?
The horizontal velocity of the projectile (and the air resistance if known) will determine the horizontal distance traveled and the time required.
Will a bullet travel the same distance straight up that it would horizontally?
No. The horizontal distance depends on how close the the ground the gun is. From the firing position, a bullet dropped to the ground will strike the ground in the same time as a bullet shot horizontally forward.
Which lines-latitude or longitude- are always the same distance no matter where they are?
It's longitude Longitude goes vertically from one point and down so it is always going to be the same distance...Latitude goes horizontally so it isn't the same distance. HOPE THIS HELPED!
Can airliner jet glide without fuel?
to a certain degree yes but it may probably go into stall. A glide is when an aircraft or object travels horizontally while dropping vertically. If it doesn't glide, then it drops vertically---i.e. a rock. If it can travel horizontally the same distance as the distance it falls, this is referred to as a 1:1 (one-to-one) glide slope. Many aircraft can not do this and will drop faster than they fly forward.

How will natural gas be harnessed?
Drilling companies drill vertically down to the desired distance, and drill horizontally into the shale. They then use hydraulic fracturing, or fracking, to loosen up the rock enough to get the gas out.
Will a ball thrown almost horizontally go the furthest?
No, this is an example of projectile motion. You should throw it at 45 degrees from the horizontal ground for it to have the maximum horizontal distance. This is because a sufficient height must be achieved, so that the ball can stay in the air longer and thus travel a longer distance while in flight.
What can be mapped onto itself by a horizontal translation?
Any function or object that has symmetry about the y-axis can be mapped onto itself by a horizontal translation. This means that if the function or object is shifted horizontally by any distance, it will still look the same.
