Problem 1 A dog starts running at a constant speed v0= 6 m/s. Initially, the dog is at a distance d= 10 m from a window. The window is located at a height h= 20 m above the ground. On top of the window there is a plant pot of mass m = 3 kg. The pot falls from the window 2 seconds after the dog starts running. a) What is the speed (inm/s2) of the pot when it reaches...

A lumberjack (mass = 98 kg) is standing at rest on one end of a floating log (mass = 215 kg) that is also at rest. The lumberjack runs to the other end of the log, attaining a velocity of +4.0 m/s relative to the shore, and then hops onto an identical floating log that is initially at rest. Neglect any friction and resistance between the logs and the water. (a) What is the velocity of the first log just...

A 2.1 kg mass is attached to a spring with a spring constant of 75.3 N/m. The spring is securely attached on the other end to a vertical wall so that the spring extends and contracts horizontally. The mass is shoved so the mass has a velocity of 3.1 m/s and the spring is streched 0.128 m from its equilibrium, or rest, position when the mass is released. Friction and air resistance are negligible. What is the greatest distance that...
