Four charges are at the corners of a square centered at the origin as follows: q at (-a, +a); 2q at (+a, +a); -3q at (+a,-a); and 6q at (-a, -a). A fifth charge +q is located at the origin and released from rest. Determine its speed when it is a great distance from the origin if a = 0.6 meter, q = 2.4 mu or micro CC, and its mass is 1.4 kilogram.
The tub of a washer goes into its spin cycle, starting from rest and gaining angular speed steadily for 9.00 s, how many revolutions does the tub turn while it is in motion
A 2.40kg mass is pushed against a horizontal spring of force constant 26.0N/cm on a frictionless air table. The spring is attached to the tabletop, Find the greatest speed the mass reaches
A force vector points at an angle of 64.9 ° above the +x axis. It has a y component of +276 Newton's (N). Find out (a) magnitude and (b) x component of the force vector.
A plucked guitar string produces a sound wave of frequency 440 Hz. (a) What is the wavelength of the sound wave (assume the speed of sound in air is 340 m/s)? (b) How much time elapses between the impacts of two adjacent compression on your eardru..
A plane leaves the airport in Galisto and flies 175 km at 68.0^circ east of north and next changes direction to fly 260 km at 48.0^circ south of east, after which it makes an immediate emergency landing in the pasture.
On a frictionless, horizontal air table, puck A (with mass 0.25 kg) is moving toward puck B (with mass 0.350 kg), that is initially at rest. After the collision, puck A has a velocity of 0.120 m/s to the left, and puck B has velocity 0.620 m/s to the..
A block of mass m = 0.875 kg is fastened to an unstrained horizontal spring whose spring constant is k = 81.3 N/m. The block is given a displacement of +0.134 m, where the + sign indicates that the displacement is along the +x axis, and then released..
