PLZ HELP WILL MARK YOU A 5) A goose can travel at a speed of 17 m/s (approximately 38 mph). If the goose's forward thrust on a calm day provides a forward force of about 5 N, calculate the force of the air resistance (friction) that is acting on the Canadian goose
AND please tell me the formula you used

If a spring has a k value of 100 newtons per meter and it is stretched 0.50 meters, what is the restoring force of the spring?

What ia the energy of an object because of its potential and kinetic energies

An alpha particle with kinetic energy 12.5 mev makes a collision with lead nucleus, but it is not "aimed" at the center of the lead nucleus, and has an initial nonzero angular momentum (with respect to the stationary lead nucleus) of magnitude l = p0 b, where p0 is the magnitude of the initial momentum of the alpha particle and b=1.40×10−12 m. (assume that the lead nucleus remains stationary and that it may be treated as a point charge. the atomic number of lead is 82. the alpha particle is a helium nucleus, with atomic number 2.) what is the distance of closest approach?
