A 320 hp car engine can deliver that maximum power at 7000 rpm. What is the engine's torque at that speed? Show your results in both m-N and ft-lb.
A force Farrowbold applied to an object of mass m1 produces an acceleration of 3.10 m/s2, What is the value of the ratio m1/m2
A bumper car with mass m1 = 116 kg is moving to the right with a velocity of v1 = 5 m/s. A second bumper car with mass m2 = 96 kg is moving to the left with a velocity of v2 = -3.8 m/s. The two cars have an elastic collision. Suppose the surface is f..
A point charge 4.20 mu C is held fixed at the origin. A second point charge 1.60 mu C with mass of 2.80×10-4 kg is placed on the x axis, 0.280 {rm m} from the origin. The second point charge is free from rest. What is its speed when its distance f..
A block of mass 0.680 kg is pushed against a horizontal spring of negligible mass until the spring is compressed a distance x
Consider a standing wave on the string with a frequency equal to the fifth harmonic (fn = nf1 with n = 5). How many nodes and antinodes does this standing wave possess.
A gamma-ray photon produces an electron-positron pair, each with a kinetic energy of 230keV. What was the energy of the photon
A bird is flying directly toward a stationary bird-watcher and emits a frequency of 1230 Hz, What is the speed of the bird
So as to simulate weightlessness for astronauts in training, they are flown in a vertical circle. If the passengers are to experience weightlessness, how fast must an airplane be moving at the top of a vertical circle with a radius of 1545 m.
Describe what are the (a) magnitude and (b) direction of the boat's velocity relative to the ground? (c) How long does the boat take to cross the river?
The potential at location A is 393 V. A positively charged particle is released there from rest and arrives at location B with a speed vB. The potential at location C is 781 V, and when released from rest from this spot, the particle arrives at B wit..
mass-spring system can oscillate with simple harmonic motion because a compressed or stretched spring has which kind of energy.
