Two cylindrical bars, each with diameter of 2.50 cm, are welded together end-to-end. One of the original bars is copper and is 0.360 m long. The other bar is gold and is 0.125 m long. What is the resistance between the ends of the welded bar at 20 oC?
Suppose an initial speed of 21.4 m/s, at an angle of 61.10° with respect to the positive x axis. Find the velocity at time t0; enter x component, after that the y component.
The student throws a ball into the air along a path that he judges to make an initial angle of 59° with the horizontal and to be in line with the track. The student's professor, who is standing on the ground nearby, observes ball to rise verticall..
Two equally charged particles, held 3.4 × 10-3 m apart, are released from rest, what are the mass of the second particle and, the magnitude of the charge of each particle
In a performance test, each of two cars takes 9.40s to accelerate from rest to 25 m/s. Car A has a mass of 1288 kg, and car B has a mass of 1767 kg. Find the net average force that acts on (1) car A and (2) car B during the test.
A professor's office door is 0.90 wide, 2.00 high, 4.00 thick; has a mass of 30, and pivots on frictionless hinges. A "door closer" is attached to door and the top of the door frame. When the door is open and at rest, the door closer exerts the torqu..
The electric field everywhere on the surface of a thin spherical shell of radius 0.780m is measured to be equal to 940 N/C and points radially toward the center of the sphere.
A ski jumper has 1.2 ´ 10 J of potential energy at the top of the ski jump. The friction on the jump slope is small, but not negligible. What can you end about the ski jumper's kinetic energy at the bottom of the jump.
The height of an empty can is H, and the mass M. The mass of a full can is m, What is the center of mass of the can as a function of x? h is the height from the bottom to the surface
A particle leaves the origin with an initial velocity of 4.20 m/s in the x direction, and moves with constant acceleration ax = -1.80 m/s2 and ay = 2.30 m/s2. a-How far does the particle move in the x direction before turning around? b-What is the..
A 220 g air-track glider is attached to a spring. The glider is pushed in 12cm against the spring, and then released. A student with a stopwatch finds that 16 oscillations take 11.5.
When a high speed passenger train traveling at 113 km/h rounds a bend, the engineer is shocked to see that a locomotive has improperly entered onto the track from a siding and is a distance D = 642m ahead.
