Two shopping carts are pushed with the same amount of force. the shopping carts have the same mass. shopping cart a is pushed with three times the force as shopping cart b. how does the force applied to the shopping carts affect their acceleration? shopping cart a accelerates three times as fast as shopping cart b. both shopping carts will accelerate at the same rate since their masses are the same. shopping cart b accelerates twice as fast as shopping cart a. shopping cart b accelerates three times as fast as shopping cart a.

When does your body conduct current more readily?

Consider a double atwood machine constructed as follows: a mass 4m is suspended from a string that passes over a massless pulley on frictionless bearings. the other end of this string supports a second similar pulley, over which passes a second string supporting a mass of 3m at one end and m at the other. using two suitable generalized coordinates, set up the lagrangian and use the lagrange equations to find the acceleration of the mass 4m when the system is released. explain why the top pulley rotates even though it carries equal weights on each side.
