The theory of special relativity explains the connection between space and time to objects that move in a straight line at a constant speed. The objects move at the speed of light. When an object approaches light speed, its mass is endless and cannot move faster than light. The most crucial postulate of Einstein's special relativity is that the laws of nature do not change in each frame of reference.

An advertisement claims that a particular automobile can "stop on a dime." What net force would actually be necessary to stop an automobile of mass 910 kgkg traveling initially at a speed of 53.0 km/hkm/h in a distance equal to the diameter of a dime, which is 1.8 cmcm? Express your answer in newtons.
a) Given the following ideal Atwood machine in an elevator accelerating down at ae = 4.9 m/s2, with m1 = 10 gram (two nickels) and m2 = 5 gram (one nickel) as shown, what is the tension T in the string in millinewton (mN)? (Hint: the upward arrow on ae is correct and just means use "positive is up" conventions for the elevator itself, so here we have ae = -4.9 m/s2 to be put into Einstein's rule that we discussed.) b) Exact same Atwood machine as the previous problem (two nickels and a nickel in an elevator accelerating down at 4.9 m/s2), but now how much time (s) does it take m1, starting from rest, to fall 25 cm relative to the inside of the elevator? I labeled it a and b because they are connected to each other. Please help, thanks!
A spacecraft cruising in space at a constant velocity of 2000 ft/s has a mass of 25,000 lbm. To slow down the spacecraft, a solid fuel rocket is fired, and the combustion gases leave the rocket at a constant rate of 150 lbm/s at a velocity of 5000 ft/s in the same direction as the spacecraft for a period of 5 s. Assuming the mass of the spacecraft remains constant, determine (a) the deceleration of the spacecraft during this 5-s period, (b) the change of velocity of the spacecraft during this time period, and (c) the thrust exerted on the spacecraft.

1. Using the Stokes’s-law equation, calculate the particle diameter, dst, of magnesium oxide powder, ρ = 3.65 g/cm3 , in an aqueous medium having a density of ρ0 = 1.05 g/cm3 at 25◦C and a viscosity of 0.013 poise (i.e., 0.013 g cm-1 sec-1 ). The particles settle a distance of 24.0 mm in 1.00 hr under gravity acceleration g of 980 cm/sec2. Hint: Remember to convert 24.0 mm/hr to cm/sec for the rate of settling of the particles.
