A 6.2 kg object is initially moving to the left at 10.8 m/s. A constant force is applied to the object over 1.29 seconds and the object ends up moving at 5.9 m/s to the left. What was the change in momentum experienced by the object?  ____________kgm/s What was the size and direction of the force applied over the 1.29 seconds?  Newtons

A bicycle has a momentum of 15 kg•m/s. What momentum would the bicycle have if it had double the mass and was moving at the same speed and in the same direction? *

The force shown in the force vs. time diagram in the figure below acts on a 2.0-kg object (N) 2 1 4 5 2 3 (a) Find the impulse of the force. N S (b) Find the final velocity of the object if it is initially at rest. m/s (c) Find the final velocity of the object if it is initially moving along the x-axis with a velocity of -1.9 m/s. m/s

(1) A large moving ball collides with a small stationary ball. The momentum  a. of the large ball decreases, and the momentum of the small ball increases.  b. of the large ball decreases, and the momentum of the small ball decreases.  c. of the small ball decreases, and the momentum of the large ball increases.  d. does not change for either ball.    (2) A sphere of mass 2 kg moving at a velocity 5 m/s strikes another sphere of mass 3 kg at rest. If they move together after collision what is their common velocity ?   (3) Two piloted satellites approach one another at a relative speed of 0.250 m/s, intending to dock. The first has a mass of 4.00×103kg, and the second a mass of 7.50×103kg. If the two satellites collide elastically rather than dock, what if their final relative velocity?
