Q. A 50.0g sample of water at 70.0 degrees C is mixed with 90.0g of water at 25.0 degrees C. What is the final temperature of the mixture?
Q. Some air is flowing from a wider tube to the narrower. There is a difference in height of the liquid in the two sides of the U-shaped tube. Why is there such a difference in height?
A test rocket is fired vertically upward from a well. A catapult gives it an initial speed of 80.6m/s at ground level. Its engines then fire and it accelerates upward at 3.80 m/s2 until it reaches an altitude of 930m. At that point its engines fai..
A rotating door is made from four rectangular sections, as indicated in the drawing. The mass of each section is 80 kg. A person pushes on the outer edge of one section with a force of F = 75 N that is directed perpendicular to the section. Find out ..
A 2.8 kg block slides along a frictionless horizontal with a speed of 5.5 m/s. After sliding a distance of 8m, the block makes a smooth transition to a frictionless ramp inclined at an angle of 43 degrees to the horizontal. The acceleration of gravit..
Presume you carry a bag of groceries weighing 148 N from your car to the kitchen, a distance of 59m, without raising or lowering the bag.
A plane leaves the airport in Galisto and flies 170 km 68 degrees east of north and after that changes direction to fly 230 km at 48 degrees south of east, after that it makes an immediate emergency landing in a pasture. When airport sends out a r..
A 45.4 kg girl is standing on a 144 kg plank. The plank, at first at rest, is free to slide on a frozen lake, which is a flat, frictionless surface. The girl begins to walk along the plank at a constant velocity of 1.60 m/s relative to the plank. Wha..
At the instant the alpha particle leaves the nucleus, the centers of the two are 7.5 apart and essentially at rest. Find their speeds while they're a great distance apart. Treat each particle as a spherical charge distribution.
A 120 kg mail bag hangs by a vertical rope 4.00 m long. A postal worker then displaces the bag to a position 2.10 m sideways from its original position, always keeping the rope taut.
A child's toy consists of a piece of plastic attached to a spring. The spring is compressed against the floor a distance of 1.2 cm, and the toy is released. If the spring constant is 103 N/m, what is the magnitude of the spring force acting on the..
