The velocity of a particle traveling along a straight line is v = vo − ks where k is constant. if s=0 when t=0, determine the position and acceleration of the particle as a function of time.

acceleration of the particle as a function of time is given as

and position of the particle as a function of time is given as

Explanation:

we have given,

at t=0, s=0

therefore initial velocity,u

u=v=

v=u+at.........(1)

we know from first equation of motion

let acceleration at time t be a(t), and position be x(t)

put value of v,u and a in equation 1

we got,

Therefore,acceleration of the particle as a function of time is given as

and position of the particle as a function of time is given as

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
