Question

A vehicle is travelling at a constant speed of 60km/h round a curve of radius 100m find acceleration?

Answer 1

Answer:

0

Explanation:

according to the definition of acce;eration it is the rate of change of velocity

as velocity depends on displacement

displacement is always 0 if the body starts and reaches at the same position

so velocity is also 0

and so as velocity is 0 any number multiplied with 0 is 0

and so acceleration is also 0

Answer 2

Answer:

1/9 m/s^2

Explanation:

The particle is performing circular motion with constant speed so tangential acceleration is 0 and centripetal acceleration is mv^2/r----(1)

V= 60kmph= 60*5/18=50/3 mps----(2)

there centripetal acceleration = 1/9 m/s^2 = overall acceleration
