Q. A crate is pulled by a force (parallel to the incline) up a rough incline. The crate has an initial speed of 1.5 m/s. The crate is pulled a distance of 7.5m on the incline by a 150 N force. The acceleration of gravity is 9.8 m/s² mu=0.15
What is the change in kinetic energy of the crate? Mass of the crate is 15 kg.
Suppose an ideal gas is in a container 3L in volume and allowed to expand by having a piston move. The final volume after the piston moves is 15L. If the gas is at first at a pressure of 1×10^5 Pa and a temperature of 300 K, and temperature is mai..
A pair of speakers separated by 0.700m is driven by the same oscillator at a frequency of 662Hz. An observer, originally positioned at one of the speakers, begins to walk along a line perpendicular to line joining the speakers. (Assume the speed o..
A person eats a dessert that contains 230 kcal. The skin temperature of this individual is 36° C and that of her environment is 21° C. The emissivity of her skin is 0.85 and its surface area is 1.3 m2. How much time would it take for her to emit the ..
An important news announcement is trans- mitted by radio waves to people who are 122 km away, sitting next to their radios, and by sound waves to people sitting across the newsroom, 1.2 m from the newscaster. Take the speed of sound in air to be 345 ..
When one gallon of gasoline is burned in a car engine, 1.18 x 10^8 J of internal energy is released. Suppose that 0.99 x 10^8 J of this energy flows directly into the surroundings (engine block and exhaust system) in the form of heat. If 6.0 x 10^5 J..
A ship has a mass of 40000 kg. its energy gives it an acceleration of 0.27 m/s while it travels a distance of 105 meters from rest. what force does the engine exert on the ship.
A thin copper rod 1 m long has a mass of 50 g. What is the minimum current in the rod that would allow it to levitate above the ground in a magnetic field of magnitude 0.100 T.
Though slow on land, the leatherback turtle holds record for the fastest water speed of any reptile: 9.78 m/s. It is also among the largest of reptiles. Assume the largest leatherback yet discovered were to swim at the top leatherback speed. If its k..
What is wave speed
A charge of +2.00 x 10^-9 C is placed at x = 0.0 m. A second charge of +4.00 x 10^-9 C is placed at x = 1.5 m.
Two cars with equal mass collide head on. One car is going 18 mph. That car is push backward about 38 feet. What is the speed of other vehicle.
Two carts with masses of 5.00 kg and 2.64 kg move toward each other on a frictionless track with speeds of 4.86 m/s and 3.46 m/s correspondingly. The carts stick together after colliding head-on. Find the final speed.
