A 32.0 kg child slides down a long slide in a playground. She starts from rest at a height h1 of 21.00 m. When she is partway down the slide, at a height h2 of 10.00 m, she is moving at a speed of 8.40 m/s. Calculate the mechanical energy lost due to friction (as heat, etc.).
A test tone used on a radio has a frequency of 951 Hz. What is the wavelength of this sound in air at normal room temperature
A 480g , 8.00-cm-diameter solid cylinder rolls across the floor at 1.50m/s. What is the can's kinetic energy
A car is traveling 72.0 km/h when the driver applies the brakes. If if car slows down uniformly with an acceleration of -4.5 m/s2, how far does the car travel before coming to rest.
neglect the initial speed of the roller coaster. A neautral water molecule in its vapor state has an electric dipole moment of magnitude 6.2x10^-30 C.m. How far apart are molecule's center of positive and negative charge.
A dockworker applies a constant horizontal force of 79.0N to a block of ice on a smooth horizontal floor. The frictional force is negligible. The block starts from rest and moves a distance 15m in a time 4.50s. What is the mass.
Four identical 7 mC charges are placed on a neutrally- charged penny, Determine the resulting potential in the center of the penny due to the four charges
A block of mass 1.90 kg is pushed 4.60 m along a frictionless horizontal table by a constant 16.0 N force directed 27.0° below the horizontal.
Determine the greatest vertical displacement of the pendulum (height). The mass lost by the rocket during these 30.0 is negligible. What impulse does an engine impart to the rocket?
A 1500kg car skids to a halt on a wet road where coefficient of friction = 0.46. How fast was car traveling if it leaves 68m long skid marks.
A 9.00 kg box hangs in static equilibrium. Find the tension in each rope. T1 on the left makes an angle of 15 degrees below the horizontal and is attached to the 9.00 kg box
The train comes to a stop 6m from the point at which it was released. What is the magnitude of train's acceleration after its wheel begins to stick.
