Question

A car of mass 1000kg rounds a curve of radius 200m. at 72km/hr . calculate the centripetal Force act on it .

Answer 1

Answer:2000 N

Explanation:

Centripetal force=mv^2/r

m-mass

v-velocity

r-radius

Velocity=72km/hr

=72×1000m/3600s

Velocity =20m/s

Centripetal force=mv^2/r

=1000×20×20/200

Centripetal force=2000 N
