The puck enters the goal and interacts with the goal- net. When the puck hits it, the net begins to move and also stretches. What two energy changes occur for net while this is happening? (Select the two changes below you think apply) (HINT: It is important to focus only what is happening to the net in this situaiton, and not what is happening to the puck)
Homework Answers
As the net which was at rest initially , comes in contact with the puck, it begins to move. As the net starts moving, the kinetic energy of puck converts into kinetic energy of the net .
As the net stretches, the net gains spring potential energy and loses kinetic energy. hence kinetic energy gets converted into spring potential energy.
Add Answer to:

the puck hits it,...

A hockey player is 16 meters from the goal when he hits the puck toward an empty net, imparting a launch speed of 41 m/s at a launch angle of 10o. The top of the goal is 1.8 m high. Does hockey player make the shot or does the puck go over the net? Show work using kinematics.

Learning Goal: To understand
the relationship between force, impulse, and momentum. The effect
of a net force ΣF⃗ acting on an object is related both to the force
and to the total time the force acts on the object. The physical
quantity impulse J⃗ is a measure of both these effects. For a
constant net force, the impulse is given by J⃗ =F⃗ Δt. The impulse
is a vector pointing in the same direction as the force vector. The
units...

and predict the corresponding motion of a particle. Potential
energy diagrams for a particle are useful in predicting the motion
of that particle. These diagrams allow one to determine the
direction of the force acting on the particle at any point, the
points of stable and unstable equilibrium, the particle's kinetic

Marginal cost-benefit analysis and the goal of the firm Ken Allen, capital budgeting analyst for Bally Gears, Inc., has been asked to evaluate a proposal. The manager of the automotive division believes that replacing the robotics used on the heavy truck gear line will produce total benefits of $524,000 (in today's dollars) over the next 5 years. The existing robotics would produce benefits of $434,000 (also in today's dollars) over that same time period. An initial cash investment of $209,600...

15. Consider the MAJOR product outcomes when 8 reacts with Nal vs. NaOH. Select the correct outcomes from the table. (Hint 1: for both Sn2 and E2 leaving group must be axial; for E2, the B-hydrogen must be 180° away from leaving group). (Hint 2: For 2 RX substrates, products depend on conjugate acid; i.e.strong acids have weak conj. bases compare to problem #20, 21). 8+ Nal yields products with --- ? 8 + NaOH yields...
