Question

WHAT IS THE NET FORCE (CENTRIPETAL FORCE) FOR A 1500 KG

CAR DRIVING 5 M/S AROUND A CURVE, 10 M IN RADIUS?

Answer 1

A :-) Given - m = 1500 kg
v = 5 m/s
r = 10 m
Solution -
F = mv^2 by r
F = 1500 x 5 x 5 by 10
( cut 5 and 10 because 5 x 2 = 10 )
F = 1500 x 5 by 2
( cut 2 and 1500 because
2 x 750 = 1500 )
F = 750 x 5
F = 3750 N
.:. The centripetal force is 3750 N.
