a) Calculate the momentum of a 1950 kg elephant charging a hunter at a speed of 7.50 m/s.  kg · m/s   (b) Compare the elephant's momentum with that of a 0.0400 kg bullet fired at a speed of 600 m/s.   (c) What is the momentum in kilograms times meters per second of the 90.0 kg hunter running at 8.00 m/s after missing the elephant?  kg · m/s

Betty (mass 47 kg) stands on an ice rink as Bubbles (her hyperactive puppy, mass 6.9 kg)) runs towards her and leaps into her arms. If they move off together with a speed of 0.77 m/s, how fast (in m/s) was Bubbles moving when Betty caught her?

A 120 kg man is standing in the middle of a skating rink holding a 2kg ball. He suddenly throws the ball eastward at 5 m/s. What is the magnitude of his momentum afterward? Assuming frictonless between his skateboots and the ice.

t (a) What is the mass of a large ship that has a momentum of 3.00 x 10 kg m/s, when the ship is moving at a speed of 46.0 km/h? kg (b) Compare the ship's momentum to the momentum of a 1200 kg artillery shell fired at a speed of 1100 m/s. Pship Pshell

Betty (mass 40 kg) stands in an ice rink as Bubbles (her puppy, mass 12 kg) runs towards her and leaps into her arms. If they move off together with a speed of 0.80 m/s, how fast (in m/s) was Bubbles moving when Betty caught her?

Two cars collide at an icy intersection and stick together afterward. The first car has a mass of 1050 kg and was approaching at 5.00 m/s due south. The second car has a mass of 900 kg and was approaching at 25.0 m/s due west. (a) Calculate the final velocity of the cars. (Note that since both cars have an initial velocity, you cannot use the equations for conservation of momentum along the x-axis and y-axis; instead, you must look for other simplifying aspects..) magnitude:    m/s direction:     (degrees) (b) How much kinetic energy is lost in the collision? (This energy goes into deformation of the cars.)

A 30.00 kg mass falls from a height of 2.000 m. The magnitude of the momentum of the mass just before it hits the ground is

At one particular moment, a 17.0 kg toboggan is moving over a horizontal surface of snow at 5.00 m/s. After 9.00 s have elapsed, the toboggan stops. Use a momentum approach to find the magnitude of the average friction force (in N) acting on the toboggan while it was moving. Need Help? Read It

in 8.43s, 168 bullets strike and embed themselves in a wall. The bullets strike the wall perpendicularly. Each bullet has a mass of 5 x 10-3 kg and a speed of 931 m/s. (a) What is the average change in momentum per second for the bullets? (b) Determine the average force exerted on the wall. (c) Assuming the bullets are spread out over an area of 2.76x 10-4 m7 obtain the average pressure they exert on this region of the wall.
