Two identical coins are initially held at height h = 11.6 m. Coin 1 is dropped at time t = 0 and then lands on a muddy field where it sticks. Coin 2 is dropped at t = 0.500 s and then lands on the field. What is the magnitude of the acceleration of the center of mass (com) of the two-coin system (a) between t = 0 and t = 0.500 s, (b) between t = 0.500 s and time t1 when coin 1 hits and sticks, and (c) between t1 and time t2 when coin 2 hits and sticks? What is the speed of the center of mass when t is (d) 0.250 s, (e) 0.750 s, and (f) 1.75 s?

Two objects are dropped simultaneously from an initial height of 100m, with an initial velocity of zero. They fall straight down. For mass 1, you can ignore air drag. For mass 2, air drag DOES affect the motion.

1. A particle of mass m and charge q is dropped from height of 3h above the ground. The particle starts from rest and its starting position is (x, y) (0,3h). At height 2h, the particle enters a uniform electric field of magnitude E pointing in the negative r direction. The magnitude of the force on the particle due to the electric field is qE. The particle exits the electric field at height h. A cup is placed at position...

1. [25 points) Idealized frictionless free fall of an object that is dropped from being at rest at i = 0. For the following question, to model the free fall of a falling rock, assume the usual idealizing simplifications for solving "free fall" problems. Consider the following experiment. A rock with a mass of m= 2 kg is dropped at the time t = 0 from a height of 140 m above ground. Assume that the rock is simply dropped...
