On a banked race track, the smallest circular path on which cars can move has a radius of 102 m, while the largest has a radius 157 m, Find the smallest and largest speed the cars can remove without the presence of friction
It is claimed that if a lead bullet goes fast enough, it can melt completely when it comes to a halt suddenly, and all its kinetic energy is converted into heat via friction. Find the minimum speed of a lead bullet (initial temperature = 39.0° C) for..
