Two people, each with a mass of 70 kg, are wearing inline skates and are holding opposite ends of a 15m rope. one person pulls forward on the rope by moving hand over hand and gradually reeling in more of the rope. in doing so, he exerts a force of 35n [backwards] on the rope. this causes him to accelerate toward the other person. assuming that the friction acting on the skaters is negligible, how long will it take for them to meet? explain your reasoning.

The metric unit of electrical power is the watt volt ampere ohm

Achild has maximum walking speed of 1.6 m/s. what is the length of the child's legs? 0.26 m

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
