15 . A car makes a 50-m-radius turn on a flat road with no banking. The car speeds up until a book on the floor overcomes friction and starts to slide outward. If the coefficient of static friction is 0.45, what was the speed of the car when the book began to slide?
The magnitude of the force required to cause an 0.04 kg object to move at 0.6 m/s in a circle of radius 1.0 m is:
Select one:
O a. 2.472 × 10-2 N
b. 3.13N
c. 1.4 x 10-2N
O d. 2.4 x 10-2 N
e. 1.4r × 10-2 N
A car is moving in a circular road (
radius of 56.1 m) with a speed of 12.3
m/s. Find the minimum static friction
