Given: M1= 75kg; M2 = 50kg; V (M1) = 10 m/s North; V (M2) = 10 m/s West

Action: Collision, two masses stick together, move at unspecified angle in M2's initial direction

Question: Find magnitude of their speed together after collision.

Expert Solution

The principle of conservation of momentum states that if two objects collide, then the total momentum before and after the collision will be the same if there is no external force acting on the colliding objects.

2. [10 pts] Consider a stable marriage instance with men M = {m1,m2,m3} and women W ={w1, w2, w3} having the following preference lists: m1 :w1 >w2 >w3m2 :w2 >w1 >w3m3 :w1 >w2 >w3 w1 :m2 >m1 >m3w2 :m1 >m2 >m3w3 :m1 >m2 >m3 If these preferences are given to the Gale-Shapley algorithm, what is the resulting set of marriages? Now, suppose w1 decides to lie to the algorithm about her preferences and instead submits the list w1 : m2...

A ball, mass m1 = 0.1 kg, is moving upwards with a speed of 10 m/s when it collides inelastically with a cup, mass m2 = 0.9 kg, that is initially at rest. After the collision the system (ball+cup) moves straight upwards without rotating. This collision occurs on Earth, and the local gravitational field points down with g = 9.8 m/s2 . (a) What is the momentum of the system before the collision? Write your final answers and neatly show...

An electron (mass m1 = 9.11 x 10-31 kg) and a proton (mass m2 = 1.67 x10-27 kg) attract each other via an electrical force. Suppose that an electron and a proton are released from rest with an initial separation d = 2.40 x 10-6 m. When their separation has decreased to 0.510 x 10-6 m, what is the ratio of (a) the electron's linear momentum magnitude to the proton's linear momentum magnitude, (b) the electron's speed to the proton's...

The intensity levels I of two earthquakes measured on a seismograph can be compared by the formula log I1/I2 = M1 – M2, where M is the magnitude given by the Richter Scale.

The intensity levels I of two earthquakes measured on a seismograph can be compared by the formula log I1/I2 = M1 – M2, where M is the magnitude given by the Richter Scale. In August 2009, an earthquake of magnitude 6.1 hit Honshu, Japan. In March 2011, that same region experienced yet another, more devastating earthquake, this time with a magnitude of 9.0. How many times greater was the intensity of the 2011 earthquake? Round to the nearest whole number.
