Calculate the centripetal force on a 2100kg car rounding a curve of 175m radius at speed of 60kph

Answer 1

Velocity ( speed ) = 60 km / h = 60 000 m / 3 600 s =

1 200 ∙ 50 m / 1 200 ∙ 3 s = 50 / 3 m / s

Fc in terms of mass, radius and velocity:

Fc = m v² / r

Fc = 2 100 ∙ ( 50 / 3 )² / 175 = ( 2 100 ∙ 2 500 / 9 ) / 175 =

( 5 250 000‬ / 9 ) / 175 = 5 250 000‬ / 9 ∙ 175 = 5 250 000‬ / 1 575

= 525 ∙ 10 000 / 525 ∙ 3 = 10 000 / 3 kg m / s² = 10 000 / 3 N = 3 333.333... N
