From a height of 4 m, a hollow sphere with a radius of 12 cm and a mass of 650 g rolls along an inclined trough (45 ° to the horizon). The system is located on Earth. [1] Find the potential [2] and [3] the kinetic energy at t0 just before the start of rolling and at the end of the slope of t1. [4] Find the momentum at the end of the road. [5] How would the momentum at the end of the slope change if the sphere slipped? Assume that the sphere is rolling in a V-shape slope/track (track sides are at right angle) . The image shows cross section of the sphere in the track.

dang that balls went far

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
