Car 1 has a mass of 1.50 × 10° kg and is moving at a constant speed of 4.00 m/s. It strikes Car 2, which is at rest and has a mass of 1.20 x 10° kg. The cars lock together and continue to roll forward. They then collide and lock together with Car 3, which is at rest and has a mass of 1.80 x 10° kg. Before First Collision Car 1 Car 2 Car 3 v, = 4.00 m/s v, = 0 m/s V = 0 m/s

3. On his walk home, Mr. Stark sees a wishing well. He takes out a 100 dollar bill, crumples it up into a ball and throws it upward over the well (at the level of the mouth of the well) and goes up 15 ft. 7 seconds after the bill leaves his hand, it reaches the bottom of the well which apparently didn't have any water after all. How deep is the well? What do you think he wanted to wish for?

3) A bungee jumper of mass 65.0 kg jumps off of a bridge with a long bungee cord tied safely and securely to their legs. The bungee cord is assumed to behave like a perfect spring. Below you can find a graph representing the bungee jumper's height above the ground as a function of time. c) Describe two assumptions that were made in this scenario, and explain how this "ideal" scenario would differ in the real world, where these assumptions are not valid.I 100 10 15 A 1000 Time (s) While stretched to its greatest length, the bungee cord is under high tension, and begins to vibrate due to resonance with the local air currents. It's observed behaviour is that of a standing wave on a string which is fixed at both ends. A camera captures an image of the bungee cord, seen below. (note that this image represents its full length) a) Determine the spring constant of this bungee cord. b) Calculate the maximum velocity of the bungee jumper during this process. d) Calculate the wavelength of the…
