A45.2-kg person is on a barrel ride, standing on the platform with her back to the wall. the 3.74-meter diameter spinning barrel makes a revolution every 1.65 seconds. determine the velocity, acceleration, net force, and the values of all individual forces. finally, indicate the direction of the net force and acceleration. use g = 9.80 m/s / s .

Which instrument is used to measure air temperature

Ashot putter releases the shot some distance above the level ground with a velocity of 12.0 m/s, 51.0 ∘above the horizontal. the shot hits the ground 2.08 s later. you can ignore air resistance. how far did she throw the shot?

An alpha particle with kinetic energy 12.5 mev makes a collision with lead nucleus, but it is not "aimed" at the center of the lead nucleus, and has an initial nonzero angular momentum (with respect to the stationary lead nucleus) of magnitude l = p0 b, where p0 is the magnitude of the initial momentum of the alpha particle and b=1.40×10−12 m. (assume that the lead nucleus remains stationary and that it may be treated as a point charge. the atomic number of lead is 82. the alpha particle is a helium nucleus, with atomic number 2.) what is the distance of closest approach?
