A 70-kg fisherman in a 120-kg boat throws a package of mass m = 15 kg horizontally toward the right with a speed of vi = 4.0 m/s as in the figure below. Neglecting water resistance, and assuming the boat is at rest before the package is thrown, find the velocity of the boat after the package is thrown. magnitude ___m/s direction___

A 3.45 kg black ball traveling 4 m/s has a head on collision with a white one at rest. Using the velocities shown, calculate the mass of the white ball, Ignore friction and air resistance. 0 m/s 4 m/s 1.4 m/s 5.7 m/s

A 2000 kg car is traveling East at 45 m/s while a 1500 kg car travels North at 30 m/s.  They collide inelastically at an intersection, stick together and move as one to the Northeast.  Assuming no other significant forces, what is the velocity of the two-car combo?     v =     m/s     at    θ =     º  North of East

A 80-kg fisherman in a 133-kg boat throws a package of mass m = 15 kg horizontally toward the right with a speed of v; = 4.0 m/s as in the figure below. Neglecting water resistance, and assuming the boat is at rest before the package is thrown, find the velocity of the boat after the package is thrown. magnitude m/s direction ---Select--- m

Two bumper cars at the county fair are sliding toward one another (see figure below). Initially, bumper car 1 is traveling to the east at 5.62 m/s, and bumper car 2 is traveling 60.0° south of west at 10.00 m/s. After they collide, bumper car 1 is observed to be traveling to the west with a speed of 3.24 m/s. Friction is negligible between the cars and the ground.   (a) If the masses of bumper cars 1 and 2 are 588 kg and 633 kg respectively, what is the velocity of bumper car 2 immediately after the collision? (Express your answer in vector form. Enter your answer to at least three significant figures.)   (b) What is the kinetic energy lost in the collision?
