A skier is pulled up a slope at a constant velocity by a tow bar. The slope is inclined at 26.0° with respect to the horizontal. The force applied to the skier by the tow bar is parallel to the slope. The skier's mass is 59.0 kg, and the coefficient of kinetic friction between the skis and the snow is 0.100. Find the magnitude of the force that the tow bar exerts on the skier.
A 2.5kg mass is attached to a spring and placed on the horizontal, smooth surface. A horizontal force of 18.4 N is necessary to hold the mass at rest while it is pulled 0.210 m from its equilibrium position.
At an outdoor market, a bunch of bananas attached to the bottom of a vertical spring of force constant 16.0 N/m is set into oscillatory motion with amplitude of 20.0 cm.
Water flows through a horizontal tube of diameter 3.0 m that is joined to a second horizontal tube of diameter 2.2 . The pressure difference between the tubes is 8.0 kpa . Find out the speed of flow in the first tube.
How strong is the electric field between the plates.
An electron and a proton are each placed at rest in a uniform electric field of magnitude 546 N/C. Compute the speed of each particle 52 ns after being free.
A certain car battery with a 14.0 V emf has an initial charge of 195 A•h. Assuming that the potential across the terminals stays constant until the battery is completely discharged, for how long in hours can it deliver energy at the rate of 184 W.
