Question 1 Soccer warm-up Go to the Soccer warm-up section in the knowledge article. Do all the exercises in order, starting with footwork and ending with your scheduled activity. Read the directions and study the pictures of the exercises before you begin. Be sure to complete the recommended number of sets and repetitions for each exercise. Answer the questions below when you have finished your warm-up and scheduled activity. Part A Which parts of the warm-up did you find were easiest? Why?

If a simple machine reduces the strength of a force, what must be increased?

Charge is distributed along the entire x-axis with uniform density λ. how much work does the electric field of this charge distribution do on an electron that moves along the y-axis from y = a to y = b? (use the following as necessary: a, b, ε0, λ, and q for the charge on an electron.)

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
