A55.0-g hard-boiled egg moves on the end of a spring with force constant k = 25.0 n/m. it is released with an amplitude of 0.300 m. a damping force fx = -bvx acts on the egg. after it oscillates for 5.00 s, the amplitude of the motion has decreased to 0.100 m.
calculate the magnitude of the damping coefficient b. express the magnitude of the damping coefficient numerically in kilograms per second, to three significant figures.

Two objects of different mass start from rest, are pulled by the same magnitude net force, and are moved through the same distance. the work done on object 1 is 900 j. after the force has pulled each object, object 1 moves twice as fast as object 2. how much work is done on object 2?

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:
