SHOW WORK A 3 kg object attached to a spring oscillates with an amplitude of 15 cm and a period of 2s. At a time t=0.5s, the object's position is x=9.1 cm.

Determine...

a) the spring constant of the spring.

b) the total energy of the system (in joules).

c) the maximum speed of the object.

d) the position of the object as a function of time. Use a cosine function.

Astone dropped into a well is heard to strike the water after 8seconds. find the depth of the well if the velocity of sound is 350m/s

The law of conservation of energy states that energy cannot be created or , energy can be from one substance to another. the first blank is ' destroyed ' and for the second blank is ' transferred '

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.1 m below the tank bottom which is a = 7.4 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute)
