    Undergrad What is the Translational Acceleration at a Point on the Rim at t=10?

    I have a physics problem that is asking about translational acceleration... it says this: "What is the magnitude of the translational acceleration at a point on the rim at t=10?" Is this referring to a=(r)(alpha) or is it referring to: a=(a_t^2+a_c^2)^1/2

    How Is Velocity and Acceleration Affected as a Carousel Slows Down?

    Did you have a chance to look at the diagrams I have attached? I am showing the initial velocity as Vi and then 2 more periods that represent slowing and stopped. Is it close to what you are describing? I am confused on how it can be linear if it is moving in a circle. Can you elaborate on...

    How Is Velocity and Acceleration Affected as a Carousel Slows Down?

    Homework Statement A carousel takes 1.5 min to complete one revolution while rotating at a constant rate. A person rides on the carousel platform at a distance 3.2m from the center. (a) From its state of constant rotation, the carousel then uniformly slows to a stop in time (delta t). Produce...

    Dimension Analysis: α,β in x=α+(2/3)βt^(3/2)

    Thank you so much. Being a new physics students I made a rookie mistake in assuming the only dimensions were the ones listed on a chart with quantities.

    Dimension Analysis: α,β in x=α+(2/3)βt^(3/2)

    I tried this approach and it made sense algebraically. However, I don't know of an SI unit associated with [x][t]^-3/2. Am I missing something?

    Dimension Analysis: α,β in x=α+(2/3)βt^(3/2)

    Homework Statement In the following expression x is a position and t represents time. What are the physical dimensions of each of the constants α and β? Also, for each what are the corresponding SI units? Homework Equations x=α+(2/3)βt^(3/2) The Attempt at a Solution I know that since x is...
