Solving the Problem of Sliding up a Ramp

In summary, the problem is asking for the minimum distance D for a frictionless track with given values for L and H. The equation for finding time and speed as functions of D using constant acceleration can be used to solve the problem.

Homework Statement



A frictionless track is to be built as shown, with L= 5.1 m and H= 2.8 m. In order to get the cart to slide from the top to the end of the track in the minimum time, how long should the distance D be? Assume that the speed of the cart on the horizontal surface is the same as at the bottom of the ramp.

The Attempt at a Solution



This is the problem given to me as homework, I discussed it with a lot of my classmates but no one is seem to be able to solve it. If I can't get an answer as a last resort I'll go see my teacher. :/

Well what is your attempt at a solution? What have you tried so far? At the very least, what have you discussed with your classmates?

welcome to pf!

hi yourrock! welcome to pf! :wink:

use the standard constant acceleration equations to find the time and the speed (all as functions of D) …

what do you get? :smile:​
 

What is the problem of sliding up a ramp?

The problem of sliding up a ramp refers to the difficulty of pushing or pulling an object up a sloping surface without it sliding back down due to the force of gravity.

What factors contribute to sliding up a ramp?

The main factors that contribute to sliding up a ramp include the weight and friction of the object, the angle of the ramp, and the force applied to move the object.

How can the problem of sliding up a ramp be solved?

There are several ways to solve the problem of sliding up a ramp, including increasing the friction between the object and the ramp, reducing the weight of the object, and reducing the angle of the ramp.

What role does friction play in sliding up a ramp?

Friction is a force that resists motion between two surfaces in contact. In the case of sliding up a ramp, increasing the friction between the object and the ramp can help prevent it from sliding back down.

How does the angle of the ramp affect sliding up a ramp?

The steeper the angle of the ramp, the greater the force of gravity pulling the object down. This can make it more difficult to push or pull the object up the ramp without it sliding back down.
