All thanks to almighty God! I have been able to log in

physicist in the house please help me with this and show your working

A motor car moves with a velocity of 20ms'1on a rough horizontal road and covers a displacement of 50m.Find the coefficient of dynamic friction between the tyre and the ground (g=10ms'2)

mathefaro

F=UR=Umg

therefore U=F/R

U=ma/mg

U=a/g

From equation of motion...... u²=2as

Since u= 20, a= ?, s= 50

a= u²/2s

a= 20²/2 × 50

a= 4

Recall: U= a/g

Since g= 10m/s²

Therefore: U= 4/10

The coefficient of friction (U) = 0.4
