A pickup truck with a steel bed is carrying a steel file cabinet. The coefficient of static friction for dry steel on steel is μs=0.800.
If the truck's speed is 12.0 m/s, determine what is shortest distance in which it can stop without the file cabinet sliding?
Explain how does a magnitude of the electrical force between a pair of charged particles change when they are brought to half their original distance of seperation?
A child is twirling a 0.0165-kg ball on a string in a horizontalcircle whose radius is 0.130 m. The ball travels once around the circle in 0.649 s. (a) Determine the centripetal force acting on the ball. (b) If the speed is doubled, by what factor..
