Question

Acar takes a turn along a curved road of radius of curvature of 50m.if the linear speed of the car is 60m/s, find the angular speed of the car?

Answer 1

Explanation:

Given : v=20m/s R=100m

dt

dv

=3m/s

2

Tangential acceleration a

t

=

dt

dv

=3m/s

2

Radial acceleration a

r

=

R

v
