A car of mass 800 kg goes round a corner of radius 65 m at a speed of 10 m/s.
a) What size force is needed to achieve this?
b) Suggest how this force is likely to be obtained.
c) What force would be needed if the driver approached the
bend at twice the speed?​

a. Centrifugal force = 1230.77 Newton.

b. Centrifugal force = mv²/r

c. Centrifugal force = 4923.08 Newton.

Explanation:

Given the following data;

Mass = 800kg

Radius = 65m

Velocity = 10m/s

a. To find the force;

Centrifugal force = (800*10²)/65

Centrifugal force = (800*100)/65

Centrifugal force = 80000/65

Centrifugal force = 1230.77 Newton.

b. The force associated with the car is generally referred to as centrifugal force because it's the force required to keep the car in a curved or circular path. It can be calculated using the formula;

Centrifugal force = mv²/r

c. To find the force at twice the speed;

Velocity = 2 * 10 = 20m/s

Centrifugal force = (800*20²)/65

Centrifugal force = (800*400)/65

Centrifugal force = 320000/65

Centrifugal force = 4923.08 Newton.

no simpler subs form complex ones. synthesise = make
