A solid cylider of mass 9.8 kg and radius 28 cm is yoked to a spring as shown. To be precise, the axle of the cylinder is attached to a horizontal spring force constant 2679 N/m. The cylinder rolls back and forth on a horizontal base without slipping. From simplicity, assume that the spring, he axle and the yoke which connects them have negligible masses compared to the cylinder itself. What is the angular frquency of the cylinder rolling back and foth around the equilibrium position?
Evalute the acceleration of each block and the tension in the string? Repeat the problem, adding a coefficient of kinetic friction between each block and the surface of 0.10.
The load-bearing piston in a certain hydraulic system has an area 49 times as large as the input piston. how large a force must be applied to the input piston
A bullet is fired at an angle of 60o with an initial velocity of 200.0 m/s. Explain how long is the bullet in the air? What is the maximum height reached by the bullet?
While a force of 6.0 N is applied, pulling the spring to the right, the elongation of the spring is 0.030m from its equilibrium position. What is the force constant of the spring
The spring constant for the tendon is the same for both groups, 33 N/mm. Illustrate what is the difference in maximum stored energy between the sprinters and the nonathletes?
Suppose you point a pinhole camera at a 15-m-tall tree that is 75m away. If the film is 22cm behind the pinhold, what will be the size of the tree's image on the film
A 0.200 kg block is placed on a vertical spring (k = 5.80x 10^3 N/m) and pushed downward, compressing the spring 0.100 m. As the block is released, it leaves the spring and continues to travel upward. What height above the point of release will bl..
The coefficient of friction between his clothes and Earth is 0.70. He slides so that his speed is zero just as he reaches the base. Evaluate how far does he slide?
