A mass is attached to a spring. It oscillates at a frequency of 4/? Hz when displaced a distance of 7.00 cm from equilibrium and released. What is the maximum velocity attained by the mass?
What will be the equilibrium temperature when a 223 g block of copper at 258 C is placed in the 178 g aluminium calorimeter cup containing 874 g of water at 13.2 C.
A 25.0 g object moving to the right at 17.0 cm/s overtakes and collides elasticity with a 7.0 g object moving in the same direction at 15.0 cm/s. find the velocity of each object after the collision
A concrete highway curve of radius 60 m is banked at a 13.0^circ angle. What is the maximum speed with which a 1300 kg rubber-tired car can take this curve without sliding? (Take the static coefficient of friction of rubber on concrete to be 1.0.)
Because the mass would not make it around the loop if released from the height of the top of the loop (do you know why?) it should be released above the top of the loop-the-loop height.
Does the change in speed of the downward-moving rock agree with the magnitude of the speed change of the rock moving upward between the same elevations? Explain physically why it does or does not agree.
present an explanation of why you selected each activity and how it can contribute to the prenatal, postpartum, and future development of each woman's child.
After being accelerated to a speed of 1.7×10 5 m/s, the particle enters a uniform magnetic field of strength 1.00 T and travels in a circle of radius 35.0 cm (determined by observing where it hits the screen as shown in the figure). The results of th..
At some automobile toll-collecting stations, a thin metal wire sticks up from the road and makes contact with cars before they reach the toll collector. What is the purpose of this wire?
A diving board of length 3{rm m} is supported at a point 1 {rm m} from the end, and a diver weighing 550 {rm N} stands at the free end. The diving board is of uniform cross section and weighs 295 {rm N}. Find out the magnitude of the force at the ..
The tension Tu in upper (taut) segment of the belt is 170 N, and flywheel has a clockwise angular acceleration of 1.67 rad/s2. Find out the tension in the lower (slack) segment of the belt.
A student yells across a street at a concrete wall. The student hears an echo 0.500 seconds later. If the speed of sound in air is 343 m/s, what is distance from the student to the wall only.
