Amassless rod of length l is hinged with a frictionless hinge at one end. at the end opposite to the hinge there is a very small mass m attached to the rod. the rod is released from rest in the horizontal position. what is the frequency f when the rod passes through the vertical position? 1. 2πsqrt(g/l)2.2g/l3.(1/2π)sqrt(2g/l) 4. (1/2π)sqrt(g/l)5. 2πsqrt(2g/l)6. sqrt(2g/l)7.g/l8. sqrt(g/l)

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.
