How to solve obtain the work required to move a 5 kg mass up a frictionless plane inclined at an angle of 30 with the horizontal for a distance of 2 m along the plane in a time of 3.5 s?

Work: don't care about time (that's power)
frictionless means don't care about length of plane
only care about height and mass -- figure 9.8 m/s*s for acceleration of gravity
F=ma
F times distance (up) = work
good luck

What is the minimum force required to prevent a ball weighing 12 lbs from rolling down a ramp which is inclined 60 degrees with a horizontal?
12 x sin 60 = 11.08 pounds
How does the inclined plane do your works faster and easier?
The reason that inclined planes allow us to reduce the force necessary to move items is because the work required to do both (Work = Force x Distance) is the same. When pushing up an inclined plane, the pusher only has to counteract the component of gravity that wants to slide the object back down the plane, instead of fighting against the entire force of gravity. Using an inclined plane decreases the force necessary to accomplish the task but increases the distance required for force against the vertical component. (An angled plane shortens the distance of travel overall).
What is the function of a period?
Period of a Periodic Function is the horizontal distance required for the graph of that periodic function to complete one cycle.
What does Inclined Plane do?
An inclined plane allows an object to be lifted through a vertical distance using less force than is required to lift the object straight up. The shallower the angle of the inclined plane, the less force is required to raise the object. The inclined plane is a very simple machine that offers a mechanical advantage. Although the force needed to raise the object is reduced, the force needs to move through a longer distance. Therefore, it takes the same amount of energy to raise the object . In fact, as there is always an amount of friction, it will actually take more energy to lift that simply lifting it straight up. The most common example of an inclined plane is a ramp used to raise vehicles to a higher level.
What is required for every graph?
A vertical and a horizontal scales are needed.
What is the use of gangplank in the simple machine?
A gangplank is also known as an inclined plane it is a flat surface whose endpoints are at different heights. By moving an object up an inclined plane rather than completely vertical, the amount of force required is reduced, at the expense of increasing the distance the object must travel. The mechanical advantage of an inclined plane is the ratio of the length of the sloped surface to the height it spans; this may also be expressed as the cosecant of the angle between the plane and the horizontal. Note that due to the conservation of energy, the same amount of mechanical energy is required to lift a given object by a given distance, except for losses from friction, but the inclined plane allows the same work to be done with a smaller force exerted over a greater distance.
What is a ramp that decreases the force required to move an object while increasing the distance the object travels?
simple machine
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.

Are staples required where cables run through holes in framing?
No, staples are not required where cables are run horizontally through holes in framing members. When the cable changes direction from horizontal to vertical runs from the last hole a staple is required, no greater distance that 16 inches from the hole.
