- During your winter snowboard run at park city you decide to try a back flip during the movement. When you very first take off on the jump you are moving at 5.4 rad/sec. As you get into the air you tuck to try and complete the trick, this is to ensure that you can decrease your radius of gyration from .51 to .27 during the flip in the air. To make the jump cooler you have a gopro on your helmet that is a distance of 0.25 from your COG where you are rotating. What is the linear velocity of that GoPro during the rotation of your flip. ?A solid uniform 45-kg ball of diameter 32.0 cm is supported against a vertical, frictionless wall with a string of length 30.0 cm as shown below.

The other end of the spring is fixed, so that the spring is horizontal. cylinder is able to roll on the table without slipping. Let's pull the mass to one side and release it so that it rolls back and forth. The Show that the motion of the center of mass is simple harmonic, and find the frequency of ocillation, w. HINT: There are two ways (at least) to do this. Each involves comparing information about this system to the simple harmonic ocillator we know, the mass on a spring. If you can get the force/torque equation to look like -kx = max or you can get the energy budget to look like /2mv? + /2kx? = ETOTAL, then the motion…Sand moves without slipping at 6.0 m/sm/s down a conveyer that is tilted at 15∘∘.

- A1 kg mass is tied to a string and is being swung in a horizontal circle. The mass has a constant angular velocity of 0.3 rad/s. The string has a Young's modulus of 10 X 106 N/m?, and the string's original length is 0.7 m long. The radius of the string is 0.05 cm. How much does the string stretch? You can think of the string as being shaped like a long, thin cylinder. 5.6 mm 2.7 mm 3.2 mm 4.7 mm 3.8 mmlet's consider the three atoms composing the molecule have different masses and coordinate, while the axis of rotation is still y-axis.
