Two masses A and B lie on a frictionless table as shown below. They are attached to either length of a light rope which passes around a frictionless pulley of negligible mass. The pulley is attached to a light string connected to a hanging mass C via a second frictionless pulley. Find the acceleration of each mass.

A skier is accelerating down a 30 degree hill at 3.60 m/s^2. How long would it take her to reach the bottom of the hill, assume she starts from rest and accelerates uniformly, if elevation change is 170m.
A violin string tuned to 485.0 Hz is found to exhibit 3.8 beats per second with a guitar string. What was the original frequency of the guitar string
a young lady runs for 20 minutes and gives off 168 kcal of heat by evaporation of water from her skin. how much water
Why does the oscillation of neutrinos directly imply that they must have a nonzero mass, since the passage of one flavor to another can only occur in massive particles? And What are the cosmological implications of these oscillations?

To avoid a rear-end collision with a slow moving vehicle ahead, you step on the accelerator and increase your angular speed to 13.4 x 10-2 rads/s in a time of 8 s. What is the tangential acceleration of the car
As a sailboat sails 53.0 m due north, abreeze exerts a constant force F1 onthe boat's sails. This force is directed at an angle west of duenorth. A force F2 of the same magnitudedirected due north would do the same amount of work on the sailboatover ..
