Banked Roads Curves on roads often are banked to help prevent cars from slipping off the road. If the
speed limit for a particular curve of radius 36.0 m is
15.7 m/s (35 mph), at what angle should the road be
banked so that cars will stay on a circular path even
if there were no friction between the road and the
tires? If the speed limit was increased to 20.1 m/s
(45 mph), at what angle should the road be banked?

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.

In science and physics what is the standard unit of measure for speed?

Atennis player used a tennis racket to hit a tennis ball with a mass of 0.25 kg with a force of 5.25 newtons. how does the force the tennis racket exerted on the tennis ball compare with the force the tennis ball exerted on the tennis racket? a. the force of the tennis racket on the tennis ball is equal in magnitude and opposite in direction to the force the tennis ball exerted on the tennis racket. b. the force of the tennis racket on the tennis ball is equal in magnitude and in the same direction as the force the tennis ball exerted on the tennis racket. c. the force of the tennis racket on the tennis ball is less in magnitude and in the same direction as the force the tennis ball exerted on the tennis racket. d. the force of the tennis racket on the tennis ball is greater in magnitude and opposite in direction as the force the tennis ball exerted on the tennis racket.
