A 6.0 kg bowling ball is sliding (without rolling) at 5.0 m/s on a level floor when it hits one end of a horizontal spring. The opposite side of the spring is attached to a rigid wall. The spring compresses a distance of 0.77 m while stopping the ball. Which of the following most closely approximates the average force that the spring applies to the ball as it comes to a stop?

Aregular polygon has angkes of size 150° each. how many side has the polygon

High schoolphysics 5+3 pts a neon light consists of a glass tube with metal wires at each end. when connected to a high-voltage source, the gas glows. if a fly lands on the glass tube, what will most likely happen? a) the fly will not feel a shock because the glass conducts any free electrons back into the gas. b) electrons will flow directly from the metal wires along the glass and shock the fly. c) the fly will not feel a shock because the glass insulates it from the electrons in the gas and the metal. d) electrons that are moving through the gas will be conducted through the glass and shock the fly.

An important dimensionless parameter concerned with very high-speed flow is the mach number, defined as v/c, where v is the speed of the object such as an airplane or projectile, and c is the speed of sound in the fluid surrounding the object. for a projectile traveling at 1170 mph through air at 50 ˚f and standard atmospheric pressure, what is the value of the mach number?
