1. What is the total magnetic flux through the plastic of the soda bottle?

Homework Statement An open plastic soda bottle with an opening diameter of 2.7 cm is placed on a table. A uniform 1.95-{\rm T} magnetic field directed upward and oriented 21^\circ from vertical encompasses the bottle. What is the total magnetic flux through the plastic of the soda bottle...
2. Bird Collision Problem

Homework Statement To protect their young in the nest, peregrine falcons will fly into birds of prey (such as ravens) at high speed. In one such episode, a 620 g falcon flying at 20.0 m/s hit a 1.40 kg raven flying at 9.0 m/s. The falcon hit the raven at right angles to its original path and...

4. Direction of velocity

Homework Statement A new circus act is called the Texas Tumblers. Lovely Mary Belle swings from a trapeze, projects herself at an angle of 53 ^\circ, and is supposed to be caught by Joe Bob, whose hands are 6.1 {\rm m} above and 8.2 {\rm m} horizontally from her launch point (the figure )...
5. Find initial velocity with accelration as a funt. of t

Homework Statement The acceleration of a particle is given by a_{x}(t)= - 1.94 m/s2 +( 3.05 m/s3 )t. Find the initial velocity v_{0x} such that the particle will have the same x-coordinate at time t= 4.00 s as it had at t=0. Homework Equations vx= v0x + the integral ax dt The...
