2. You are designing a roller coaster in which a car will be pulled to the top of a hill of heighth and then, starting from a momentary rest, will be
released to roll freely down the hill and toward the peak of the next hill,
which is 1.1 times as high. Will your design be successful? Explain your
answer

Three charge are arranged as shown in the diagram. the magnitude of the net electrical force acting on the +6 uc charge, rounded to the tenths place, is .

Why are graphs useful when interpreting data

The man of mass m1 and the woman of mass m2 are standing on opposite ends of the platform of mass m0 which moves with negligible friction and is initially at rest with s = 0. the man and woman begin to approach each other. derive an expression for the displacement s of the platform when the two meet in terms of the displacement x1 of the man relative to the platform.
