The 6-lb steel cylinder A and the 10-lb wooden cart B are at rest in the position shown when the cylinder is given a slight nudge, causing it to roll without sliding along the top surface of the cart. Neglecting friction between the cart and the ground, determine the velocity of the cart as the cylinder passes through the lowest point of the surface at C.
An electron with a speed of 5.83 x 108 cm/s enters an electric field of magnitude 4.92 x 103 N/C, traveling along the field in the direction that retards its motion.
A ball is thrown straight upward and returns to the thrower's handafter 2.60 s in the air. A second ball isthrown at an angle of 32.0° with the horizontal. At what speed must thesecond ball be thrown so that it reaches the same height as the onethrow..
Two infinite positively charged plates with a uniform chargedensity of 6.80 μC/m2 are placedparallel to the yz-plane with one plane passing through x = 0.65cm and the other through x = -0.65 cm, as shownin the diagram below.
a solid cylinder rolls down an inclined plane without slipping. what is the angle of the incline to the horizontal
A heat engine operates among 40°C and 380°C. Being a real engine, its efficiency is only 60 percent of that theoretically possible for a Carnot engine at these temperatures. If it absorbs heat at a rate of 60 kW, at what rate does it exhaust heat?
A 1.2 kilogram object moving with a speed of 8m/s collides perpendicularly with wall and emerges with a speed of 6m/s in the opposite direction, find the magnitude of the average force on the object by the wall
A company is producing an interface network that they claim would result in an RIN of 600 Ω ± 2% and ROUT of 16, 8, or 4 Ω ± 2%-depending on whether the connected speakers are 16, 8, or 4 Ω-selectable via a built-in switch.- Prove or disprove their c..
Consider a simple pendulum with L = 2.4 m and m = 1.8 kg. Suppose the mass is initially at rest at the lowest point on its trajectory when it is given an impulse such that it then has a velocity of 0.17 m/s. What is the total mechanical energy of the..
the temperatures indoors and outdoors are 303 and 313 k respectively. a carnot air conditioner deposits 6.64 105 j of
