6. (BONUS) Two particles each with mass m = 0.4 kg, are fastened to each other, and to a rotation axis at 0, by the two thin rods, each of length d and mass M = 1.5 kg as shown below. The combination rotates around the rotation axis with angular speed w = 0.2 rad/s. The total moment of inertia of the system measured about O is 2.3 x 10-4 kg m?. (Hint: The moment of inertia of a thin...

Question 3, thanks !
the mass move when no longer in o 3. A 1750 kg car moving to the right at 1.5 m/s collides with a 1450 kg car moving to the left at 1.1 m/s. Afterwards the heavier car is moving to the right with speed 0.25 m/s. What is the speed of the lighter car after the collision? It has a 50 g mass at the left end and a 70 g in the moment of
Hi, need some help with full workings for this question,
thanks.
Question 9 10 pts A uniform thin straight rod of mass m = 2.96 kg and length L = 1.28 m can oscillate freely in a verticle plane about one of its end O, as a compound pendulum. Using parallel axis theorem, calculate the moment of inertia of the rod I in kg m2, about an axis through the end O and perpendicular to the rod. Give your answer...
