5.6: A 1000 kg car traveling with a speed of 144 km /h round a curve of radius 100 m. Find the necessary centripetal force?
change speed to m/s
force=mass*v^2/radius
To find the necessary centripetal force acting on the car, we can use the formula for centripetal force:
Centripetal force = (mass × velocity²) / radius
Given:
Mass of the car (m) = 1000 kg
Velocity of the car (v) = 144 km/h = 40 m/s (since 1 km/h = 1000 m/3600 s)
Radius of the curve (r) = 100 m
Now, substitute these values into the formula:
Centripetal force = (1000 kg × (40 m/s)²) / 100 m
Simplify the equation:
Centripetal force = (1000 kg × 1600 m²/s²) / 100 m
Centripetal force = 1600000 N
Therefore, the necessary centripetal force acting on the car is 1600000 Newtons.
