Homework Statement A block of mass m rests on a horizontal table and is attached to a spring of force constant k. The coefficient of friction between the block and the table is mu. For this problem we will assume that the coefficients of kinetic and static friction are equal. Let the...

Homework Statement We hope to use Atwood's machine to measure gravitational accleration with an accuracy of 5% [(Delta g)/g = 0.05]. Mass m1 is heavier than m2 and it falls through a distance L. We are able to measure time with accuracy of (Delta t) = 0.1s. If we say, for any x, (delta...

What do you mean by y''(t)? Did you mean x(t)" ?? I also don't know what the chain rule has to do with this problem but the instruction was to utilize this rule when solving the problem =< Could you please think a little bit more about the relevance of the chain rule to this problem...

I thought of sine and cosine fuction in a simple harmonic motion. But how can I relate them to the chain rule?

Homework Statement Acceleration of an object is described by a function of x, a(x) = bx. (b is a constant 2 sec^-2) 1. If the speed at x=1m is zero, what is the speed at x=3m? 2. How long does the travel from x = 1m to x = 3m takes? Homework Equations chain rule : dr/dt =...
