A 4,600 kg open train car is rolling on frictionless rails at 21.1 m/s when it startspouring rain. A while later the car's speed is 19.5 m/s.What mass of water has collected in the car?Provide your answer in appropriate units of meters (m), seconds (s), kilograms (kg),radians (rad) or combinations thereof, such as m/s or m/s^2. Use at least threesignificant figures in your answer, do not use scientific notation. Using moresignificant figures will not be considered incorrect; using fewer may lead to errorsdue to rounding.

The experiment done in lab is repeated, using a ball that has unknown mass m. You plot your data in the form of f 2 versus M/L, with f in rev/s, M in kg, and L in m. Your data falls close to a straight line that has slope 6.69 m/(kg · s2). Use g = 9.80 m/s2 and calculate the mass m of the ball.
A rotating star collapses under the influence of gravitational forces to form a pulsar. The radius of the pulsar is 5.00 × 10−4 times the radius of the star before collapse. There is no change in mass. In both cases, the mass of the star is uniformly distributed in a spherical shape. If the period of the star’s rotation before collapse is 4.00 × 104 s, what is its period after collapse?

A thin metal rod of mass 1.8 kg and length 0.9 m is at rest in outer space, near a space station (see figure below). A tiny meteorite with mass 0.08 kg traveling at a high speed of 210 m/s strikes the rod a distance 0.2 m from the center and bounces off with speed 60 m/s as shown in the diagram. The magnitudes of the initial and final angles to the x axis of the small mass's velocity are θi= 26° and θf= 82°. Afterward, what is the velocity of the center of the rod? (Express your answer in vector form.) Afterward, what is the angular velocity ω→ of the rod? (Express your answer in vector form.)

Aliens declare war on Earth by dropping an asteroid on our planet. The asteroid starts at rest from a distance of 37 x 106 m from the center of Earth. Calculate the speed with which the asteroid hits Earth's surface, in km/s. Use that G = 6.7 x 10-11 N m2 / kg2, MEarth = 6 x 1024 kg, and REarth = 6 x 106 m. (Please answer to the fourth decimal place - i.e 14.3225)
A package of mass 7 kg sits at the equator of an airless asteroid of mass 4.0 1020 kg and radius 5.9 105 m. We want to launch the package in such a way that it will never come back, and when it is very far from the asteroid it will be traveling with speed 188 m/s. We have a large and powerful spring whose stiffness is 2.1 105 N/m. How much must we compress the spring?
