Question

A car with a mass of 2,000 kilograms is moving around a circular curve at a uniform velocity of 25 meters per second. The curve has a radius of 80 meters. What is the centripetal force on the car?

A. 703 N
B. 15,625 N
C. 20,250 N
D. 625 N

Answer 1

your answer is B. 15,625 N

i just took the test

Answer 2

F=(m*V²)/r
F=centripetal force
m=mass of the object going in a circle
v=object´s velocity
r=radius of circle of curve

m=2000 Kg
v=25 m/s
r=80 m

F=[2000 Kg*(25 m/s)²] / 80 m=15625 N

answer is 15625 N
