At what speed do a bicycle and its rider, with a combined mass of 120 kgkg , have the same momentum as a 1800 kgkg car traveling at 4.6 m/sm/s

69m/s

Explanation:

Step one:

given data

mass of a bicycle and its rider m1=120 kg

mass of car m2=  1800 kg

velocity of car= 4.6m/s

Required

The velocity of the  bicycle

Step two:

The momentum expression is m1v1= m2v2

make v1 subject of the formula, divide both sides by m1

v1= m2v2/m1

v1= 1800*4.6/120

v1= 8280/120

v1=69m/s

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
