The safe slides with a constant speed if Clyde pushes from behind with 399 N of force while Bonnie pulls forward on a rope with 363 N of force. What is the safe's coefficient of kinetic friction on the bank floor?
A 46.5-cm-diameter circular loop is rotated in a uniform electric field until the position of maximum electric flux is found. The flux in this position is measured to be 5.21 105 N · m2/C. What is the magnitude of the electric field?
One mole of air at 340 K confined in a cylinder under a heavy piston occupies a volume of 5.4 L. The heat capacity of air under constant volume is 5/2R. Find the new volume of the gas if 3.2 kJ is transferred to the air.
Question: It takes you 9.5 minutes to walk with an average velocity of 1.2 m/s to the north from the bus stop to museum entrance. What is your displacement?
A stone thrown horizontally from the top of a 19-m tower hits the ground at a point 18 m from the base of the tower. (Ignore any effects due to air resistance.) (a) Find the speed at which the stone was thrown.
Two equally charged particles are held 3.2 x 10^3 m apart and then released from rest. The initial acceleration of the first particle is observed to be 7.0 m/s^2 and that of the second to be 9.0 m/s^2. The mass of the first particle is 6.3 x 10^7
A 1400kg wrecking ball hangs from a 20m -long cable. The ball is pulled back until the cable makes an angle of 23.0 with the vertical. By how much has the gravitational potential energy of the ball changed?
A slide projector needs to create a 98-cm-high image of a 2.0-cm-tall slide. The screen is 300cm from the slide. Assume that the projector has a thin lens. (a) What focal length does the lens need? (b) How far should you place the lens from the s
