A simple Atwood's machine uses two masses, m1 and m2. Starting from rest, the speed of the two masses is 8.0 m/s at the end of 4.0 s. At that instant, the kinetic energy of the system is 60 J and each mass has moved a distance of 16.0 m. Determine the values of m1 and m2.

A2000 kg car is rounding a curve of radius 200 m on a level road. the maximum frictional force the road can exert on the tires of the car is 4000 n. what is the highest speed at which the car can round the curve?

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass
