A block is on a frictionless horizontal table, on earth. This block accelerates at 7.9 m/s2 when a 40 N horizontal force is applied to it. The block and table are then set up on the moon where the acceleration due to gravity is 1.62 m/s2. A horizontal force of 20N is applied to the block when it is on the moon. What acceleration does this force impact to the block?
A 10.0 g ball of claytraveling east at 5.50 m/scollides and sticks together with a 60.0 g ball of claytraveling north at 3.00 m/s. What is the speed of the resulting ball of clay
The motion of peg P is constrained through the lemniscate curved slot in OB and by the slotted arm OA.
A ramp inclined at 60.0 degrees with respect to the horizontal rests on a floor. The mass of the ramp is 10.kg, and the coefficent of static friction between the bottom of the ramp and the floor is .8. A 5.0 kg block is then placed on the inclined..
A geodesic dome constructed with an aluminum framework is a nearly perfect hemisphere; its diameter measures 56.0 m on a winter day at a temperature of 12.5°C.
Pendulum 2 has a string twice as long as pendulum 1. If we define x as the distance traveled by the bob along a circle away from the bottom, how does the k of pendulum 2 compare with the k of pendulum 1? Give a numerical ratio.
an ideal gas initially at 20degc and 187 kpa has a volume of 4.60 l. it undergoes a quasi-static isothermal expansion
Three 7 kg masses are located at points in the xy plane. What is the magnitude of the resultant force (caused by the other two masses) on the mass at the origin? The universal gravita- tional constant is 6.6726 x 10-11 N . m2/kg2. Answer in units ..
A block of mass 10 kilogram is pulled by an 80 Newton force across a table top. evaluate the magnitude of the acceleration of the block
At what point the electric potential zero. A sphere of mass 1.9 × 10-4 kg is suspended from a cord. A steady horizontal breeze pushes the sphere so that the cord makes a constant angle of 17° with the vertical. Find (a) the magnitude of that push a..
Three forces are applied to a solid cylinder of mass 12 kg (see the drawing). The magnitudes of the forces are F1 = 15 N, F2 = 24 N, and F3 = 16 N. Find the magnitude of the angular acceleration of the cylinder
A package in an airplane moving horizontally at 275 m/s is dropped while the altitude is 766 meters. How far forward from the spot over which it was dropped does the package land.
A 8-m long wire with a mass of 10 g is under tension. A transverse wave for which the frequency is 450 Hz, the wavelength is 0.9m, and the amplitude is 8.6 mm is propagating on the wire. What is the maximum transverse acceleration of a given point..
