Chapter 19, Problem 10P
Sodium ions (Na+) move at 0.851 m/s through a blood-stream in the arm of a person standing near a large magnet. The magnetic field has a strength of 0.254 T and makes an angle of 51.0° with the motion of the sodium ions. The arm contains 100 cm3 of blood with a concentration of 3.00 × 1020 Na+ ions per cubic centimeter. If no other ions were present in the arm, what would be the magnetic force on the arm?

In a naval battle, a battleship is attempting to fire on a destroyer. The battleship is a distance
d1 = 2,150 m
to the east of the peak of a mountain on an island, as shown in the figure below. The destroyer is attempting to evade cannon shells fired from the battleship by hiding on the west side of the island. The initial speed of the shells that the battleship fires is
vi = 245 m/s.
The peak of the mountain is
h = 1,840 m
above sea level, and the western shore of the island is a horizontal distance
d2 = 250 m
from the peak. What are the distances (in m), as measured from the western shore of the island, at which the destroyer will be safe from fire from the battleship? (Note the figure is not to scale. You may assume that the height and width of the destroyer are small compared to d1 and h.)

- You are working with a movie director and investigating a scene with a cowboy sliding off a tree limb and falling onto the saddle of a moving horse. The distance of the fall is several meters, and the calculation shows a high probability of injury to the cowboy from the stunt. Let's look at a simpler situation. Suppose the director asks you to have the cowboy step off a platform 2.55 m off the ground and land on his feet on the ground. The cowboy keeps his legs straight as he falls, but then bends at the knees as soon as he touches the ground. This allows the center of mass of his body to move through a distance of 0.660 m before his body comes to rest. (Center of mass will be formally defined in Linear Momentum and Collisions.) You assume this motion to be under constant acceleration of the center of mass of his body. To assess the degree of danger to the cowboy in this stunt, you wish to calculate the average force upward on his body from the ground, as a multiple of the cowboy's…arrow_forwardA box of mass m = 2.00 kg is released from rest at the top of an inclined plane as seen in the figure.
