Draw the distribution of charge for the conductor(s) in your pattern. Remember that electric field lines begin on positive charges and terminate on negative charges. A higher field line density implies a larger charge, and a lower field line density implies a smaller charge. Write a + where each line begins and a – where each line terminates.

Using the given data table, calculate the acceleration of the skateboarder. you can use either form of the equation below?

The 10-kg double wheel with radius of gyration of 125mm about o is connected to the spring of stiffness k = 600 n/m by a cord which is wrapped securely around the inner hub. if the wheel is released from rest on the incline with the spring stretched 225 mm, calculate the maximum velocity v of its center o during the ensuing motion. the wheel rolls without slipping

Consider a system to be two train cars traveling toward each other. what is the total momentum of the system before the train cars collide?   kg • what must the total momentum of the system be after the train cars collide?   kg •
