Question

a car is traveling at 60m/s on a curved road of 1200m it is increasing its speed at the rate of 4m/s2 the acceleration of car is​

Answer 1

Answer:

To Given,

at=4m/s2

v=60m/s

r=1200m

Radial acceleration, ar=rv2

ar=120060×60=3m/s2

The acceleration of the car is

a=(at)2+(ar)2

a=(4)2+(3)2=25

Solutions ,

a=5m/s2
