A shell is fired from the ground with an initial speed of 1.62 ? 103 m/s at an initial angle of 58° to the horizontal.
(a) Neglecting air resistance, find the shell's horizontal range.
The speed of a bullet as it travels down the barrel of a rifle toward the opening is given by v = (-5.30 107) t 2 + (3.15 105) t, where v is in meters per second and t is in seconds.
A magnetic field has magnitude of 10 T and can be used to store energy. Find what magnitude of electric field one should use instead of this magnetic field to store the same amount of energy per volume
You normally drive on the freeway between San Diego and Los Angeles at an average speed of 91 km/h (57 mi/h), and the trip takes 2 h and 42 min. How much longer does the trip take
a car can decelerate at -4.80 ms2 without skidding when coming to rest on a level road. what would be the magnitude of
An astronaut of mass 73 kg pushes off a satellite of mass 420 kg, exerting a force of 120 N for the 0.82 s they are in contact. What is the speed of the astronaut after they have separated
On the screen of a multiple-slit system, the interference pattern shows bright maxima separated by 0.86° and seven minima between each bright maximum. How many slits are there
Suppose the charge of one is increased by twenty seven times while the charge of the other is reduced to one-third its initial value. What would their separation distance have to be changed to in order to keep the force between them the same?
A mass-spring system oscillates on a horizontal frictionless surface with an amplitude of 3.06 cm. If the spring constant is 260 N/m and the mass is 0.470 kg, determine the mechanical energy of the system
A generator has a square coil consisting of 217 turns. The coil rotates at 104 rad/s in a 0.146-T magnetic field. What is the length of one side of the coil
A beam of monochromatic light is diffracted with a slit of width 0.630 mm. The diffraction pattern forms on a wall 1.00 m beyond the slit. The width of the central maximum is 1.70 mm. Compute the wavelength of the light.
The tune-up specifications of a car call for the spark plugs to be tightened to a torque of 48Nm. With what force must you pull
The charge is on the inside surface. The field inside the shell is zero. Inside the metal the field is strongest. Only positive charges can be on the outside surface. The field on the outside is perpendicular to the surface.
