Acart is attached to a string and the other end of the string is attached to a weight that is free to fall. the cart is initially released from rest, and travels a distance of 0.521 m m before hitting a stopper. the cart's final speed was 0.931 m/s . the inertia of the weight is 0.115 kg , while the inertia of the cart is 1.000 kg . for the next 4 parts consider a system of the earth, the weight, the cart, the string, and the track. assume the track does not move relative to the earth.1- what is the final speed of the weight? 2- what is the change in kinetic energy of the system? 3- what is the change in potential energy of the system? 4- what is the change in thermal energy of the system due to friction?

The illuminance of a surface varies inversely with the square of its distance from the light source. if the illuminance of a surface is 120 lumens per square meter when its distance from a certain light source is 6 meters, by how many meters should the distance of the surface from the source be increased to reduce its illuminance to 30 lumens per square meter?
