A group of students have measured the time it takes for a cart to travel some distance along a level track. Their best estimate of the relative error in the time measurement is 1.0 % and that of the distance measurement is 2.0 %. What is the best estimate of the relative error in their determination of the cart´s speed?
A guitar string is 90 cm long and has a mass of 3.6g . The distance from the bridge to the support post is L=62cm, What is the fundamental frequency of this string
At t=0 a grinding wheel has an angular velocity of 30.0 rad/s. It has a constant angular acceleration of 31.0 rad/s^2 until a circuit breaker trips at time t = 2.00 s. From then on, it turns through an angle 428 rad as it coasts to a stop at constant..
