Question

A bus decreases its speed from 80 kilometres per hour to 60 km per hour in 5 seconds, find the acceleration of the bus.​

Answer 1

Answer:

Given that U= initial velocity= 80 km/h = 22.2 m/s v= final velocity = 60 km/h = 16.7 m/s t= time = 5 s We have to find a= acceleration = ? a=v-u/t a= 16.7-22.2/5 a= -5.5/5 Therefore, accelaration a =-1.1 m/s^2

Answer 2

Answer:

In Newtonian mechanics, the centrifugal force is an inertial force that appears to act on all objects when viewed in a rotating frame of reference. It is directed away from an axis which is parallel to the axis of rotation and passing through the coordinate system's origin
