A hunter is testing 3 new arrowheads. He hangs a watermelon from tree using a rope. When the arrow hits the watermelon it swings upward. The maximum angle that the rope makes with the vertical is different for each arrowhead the hunter tests. All the arrows have the same mass m and is shot with the same velocity v0. Each of the 3 arrowheads are
made of different materials, and as a result, react differently when striking the watermelon.
Pointy arrow: Strikes the watermelon and remains embedded, while the watermelon swings to angle Opointy
Through arrow: Goes all the way through the watermelon and continues traveling
away from the hunter, while the watermelon swings to angle Othrough
Bouncy arrow. Bounces off the watermelon back toward the hunter, while the watermelon swings to angle bouncy
Rank the three angles 8 pointy. Othrough and Obouncy from greatest to least. Thoroughly explain your reasoning for your ranking below.

Aperson gives a shopping cart an initial push along a horizontal floor to get it moving, and then lets go. the cart travels forward along the floor, gradually slowing as it moves. consider the horizontal force(s) on the cart while it is moving forward and slowing. which of the following statements is correct? (a) both a forward and a backward force are acting on the cart, but the forward force is larger. (b) only a forward force is acting which diminishes with time. (c) both a forward and a backward force are acting on the cart, but the backward force is larger. (d) only a backward force is acting, no forward force.

Large electric fields in cell membranes cause ions to move through the cell wall. the field strength in a typical membrane is 1.0 x 10 7 n/c. what is the magnitude of the force on a calcium ion with charge +e? what is its acceleration? is it possible for a particle with the same charge as as calcium to have a different acceleration if placed at this location? what would change the acceleration: mass of the particle? diameter of the particle?
