A 1.7kg block oscillates on a spring with spring constant 16N/m . At t = 0 s the block is 20 cm to the right of the equilibrium position and moving to the left at a speed of 100 cm/s.
Determine the period of the oscillation.
A ladder 7.09 m long leans against the side of a building. If the ladder is inclined at an angle of 79.50° to the horizontal, what is the horizontal distance from the bottom of the ladder to the building.
A sample of helium behaves as an ideal gas as it is heated at constant pressure from 273 K to 343 K. what is the mass of helium present
Consider a string with length 36 cm. The two ends are attached to the ceiling, separated by distance 30.0 cm. A 1 kg mass is attached to the string at distance 15 cm from the left end. Then the mass hangs suspended in Earth's gravity. (a) Determin..
