Question

A car goes round a circular track of radius 20m with a speed 40ms-1 what will be angular speed of the car ​

Answer 1

r = 20 m

v = 40 m/s

W = v/r

W = 40/20 = 2 rad /s

Answer 2

Answer:

Velocity v=40m/s radius r=400m dtdv =3m/s2 Centripetal acceleration ac=rv2=4 001600ac=4m/s2 Tangential acceleration ...
