Finding the Equation of c in a Moving Wedge with a Particle

In summary, the conversation is about a question regarding obtaining an equation for c in Method 1 part c of Q2. The person has been struggling for a few days and their friends suggest that there may be a mistake in the question. The issue is resolved when it is pointed out that the equation for the wedge neglects the tension in the string.

I have obtain all eqtn I need but I cannot figure out how to get the equation of c.
I have been trying for few days and my friends tell me that it is possible that Dr made a mistake. Since without part c, we can still do part d easily.

Can anyone help me to see weather there are any error in the question?

My only comment is that your equation for the wedge neglects the tension in the string.

FAQ: Finding the Equation of c in a Moving Wedge with a Particle

What is a moving wedge with a particle?

A moving wedge with a particle refers to a system in which a wedge-shaped object is moving with a constant velocity and a particle is placed on the wedge and moves along with it.

How does the motion of the particle on the wedge change?

The motion of the particle on the wedge changes based on the angle of the wedge, the velocity of the wedge, and the position of the particle on the wedge. The motion can range from simple back and forth motion to circular motion.

What is the relationship between the motion of the particle and the angle of the wedge?

The angle of the wedge determines the direction and magnitude of the force acting on the particle, which in turn affects its motion. A steeper angle will result in a greater force and a more dramatic change in motion.

How does the mass of the particle affect its motion on the moving wedge?

The mass of the particle does not significantly affect its motion on the moving wedge, as long as the wedge is moving with a constant velocity. However, a heavier particle may require a greater force to move it on the wedge.

Can the motion of the particle on the moving wedge be predicted?

Yes, the motion of the particle on the moving wedge can be predicted using mathematical equations such as Newton's laws of motion and the principles of dynamics. These equations can be used to calculate the velocity, position, and acceleration of the particle on the wedge at any given time.
