Let’s say you are now at the bottom of the highest hill. assuming no energy is lost, how much kinetic energy would you have?

Zeros that follow non-zeros numbers and are also to the right of a decimal point are significant

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.

Photons with the highest energy have the longest period
