Gabriel is running at a speed of 8 meters per second (m/s). If Gabriel weighs 800 newtons (N), what is the magnitude of the momentum of the system?

Two people, each with a mass of 85.00 kg, are paddling their canoe downstream with a speed of 1.520 m/s relative to the water, in a river that flows with a speed of 2.790 m/s with respect to the shore. What is the magnitude of the total momentum of the people, in kg⋅m/s, with respect to the shore?

A radioactive nucleus at rest decays into a second nucleus, an electron, and a neutrino. The electron and neutrino are emitted at right angles and have momenta of pe = 9.26×10−23 kg⋅m/s and pν = 5.98×10−23 kg⋅m/s , respectively.   Determine the magnitude of the momentum of the second (recoiling) nucleus. Determine the angle between the momentum of the electron and the momentum of the second (recoiling) nucleus.

Your answer is partially correct. Docking a Spaceship. You and your crew must dock your 2.75 x 104 kg spaceship at Spaceport Alpha, which is orbiting Mars. In the process, Alpha's control tower has requested that you ram another vessel, a freight ship of mass 1.80 × 104 kg, latch onto it, and use your combined momentum to bring it into dock. The freight ship is not moving with respect to the colossal Spaceport Alpha, which has a mass of 1.85 x 107 kg. Alpha's automated system that guides incoming spacecraft into dock requires that the incoming speed is less than 2.0 m/s. (a) Assuming a perfectly linear alignment of your ship's velocity vector with the freight ship (which is stationary with respect to Alpha) and Alpha's docking port, what must be your ship's speed (before colliding with the freight ship) in order that the combination of the freight ship and your ship arrive at Alpha's docking port with a speed of 1.65 m/s? (b) What will be the velocity of Spaceport Alpha when the…

If a rainstorm drops 15.2 cm of rain over an area of 1.81 km2 in the period of 1 hour, what is the momentum of the rain that falls in one second?  Assume the terminal velocity of a raindrop is 10 m/s and the density of rainwater is 1000 kg/m3.

Part 1: a 30 kg gun is standing on a frictionless surface. The gun fires a 49.8 g bullet with a muzzle velocity of 324 m/s. The positive direction is that of the bullet. Calculate the momentum of the bullet immediately after the gun was fired. Answer in units of kg•m/s.  Part 2: Calculate the momentum of the gun immediately after the gun was fired. Answer in units of kg•m/s. Part 3: Calculate the kinetic energy of the bullet immediately after the gun was fired. Answer in units of J. Part 4: Calculate the kinetic energy of the gun immediately after the gun was fired. Answer in units of J.
