A car of mass 1790 kg is traveling without slipping on a flat, curved road with a radius of curvature of 34 m. If the car's speed is 15 m/s, illustrate what is the frictional force between the road and the tires?
A shotgun fires a large number of pellets upward, with some pellets traveling very nearly vertically and others as much as 1.0o from the vertical. suppose that the initial speed of the pellets is uniformly 150ms-1 and ignore air resistance.
Sam, who's mass is 79 kg, takes off across level snow in his jet powered skis. The skis have a thrust of 204 N and a coefficient of kinetic friction on snow of 0.1. Unfortunatately the skis run out of fuel after only 13 s.
A 2-kg book with no initial velocity slides down an inclined plane with an angle of 20 degrees a total of 2 meters. The force of friction does 10 Joules of work, what is the final kinetic energy of the system as the book reaches the bottom of the ..
Find out the angle theta_1 through which the flywheel will have turned during the time it takes for it to accelerate from rest up to angular velocity omega_1.
Determine the simple harmonic motion of the spring what ac velocity is ball moving
A scaffold of mass 80.0kg and length 5.10 m is supported in a horizontal position by a vertical cable at each end.
The other string is plucked in a different location, primarily exciting the 5th harmonic. The resulting sounds give rise to a beat frequency of 342 Hz. What is the wave propagation speed on the guitar strings?
Estimate approximately the angular deflection of the muon's trajectory, given that the rest mass of muon is 100Mev and that the saturation magnetization in iron is equivalent to 1.6 x 10^23 electron moments per cm^3.
Get the expression for how moving clocks run slowly when seen by observers at rest.
Displacement d2 is in the xz plane 30° from the positive direction of the x axis, has a positive z component, and has magnitude 1.10 m.
What is the magnitude of the apparent weight of a 66 astronaut 4500 from the center of Earth's Moon in a space vehicle moving at constant velocity?
The spheres are given the same electric charge Q and it is found that they come to equilibrium when each string is at an angle of 5 with the vertical. Each string is 30 cm long.
