Aball is thrown onto a rough floor at an angle theta. if it rebounds at an angle phi and the coefficient of kinetic friction is determine: (a) the coefficient of restitution e. (b) further simplify the expression if theta = phi = 45°. (c) from the previous part, determine the coefficient of friction if = 0.6. neglect the size of the ball. hint: show that during impact, the average impulses in the x and y directions are related by = . since the time of impact is the same, δ = δ or = .

the cellphone, they would then know if the killer would have contacted them or always hated them. or if it was a breakup. but if that is not the case, then it would be the clothing. to put in a bullet, it would have to be put in by hands. hands have finger prints which, would have giving you the answer of who done it.

explanation:

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
