Question

4. A car of mass 500 kg is moving on
a circular track of radius 10 m with
120 rpm calculate the centripetal
force on the car​

Answer 1

Answer:

Momentum, p=mv=300×60=18000kg m/s

(directed along the tangent to the circle)

Angular momentum, L=r×p

L=rpsinθ,θ=90∘

L=rp=100×18000=18×155kg m2s−1.
