A car moves at a constant speed of 56.4 km per hour. How much distance does it cover in 3.5 hours ?

Explanation

a. Force on the particle when the fan is at fall speed
`F_(n)= m omega^(2)R = ((1)/(1000)) ((2 pi xx 1500)/(60))^(2) ((60)/(100)) = (3)/(2) pi^(2) N`
b. The friction force excets this force
c. `F_("particle") = F_(n) = (1)/(2) pi^(2)`
