Answer:
An East Coast location was desirable because any rockets leaving Earth's surface and traveling eastward get a boost from the Earth's spin. A West Coast location would either send rockets over populated areas or have to contend with launching against the direction of the spin.
Explanation:
I do not have a answer for What is the launch window. Sorry.
An impact which stops a moving object must do enough work to take away its kinetic energy, so extending the distance moved during the collision reduces the impact force.
p = mv so this question pertains to conservation of momentum.
The momentum of the car is 1320*12 = 15840kgms^-1
For the sake of easiness and the fact negatives are annoying, I will assume east to be positive.
So we know 9.4m - 15840 = (1320+m)*1.5
9.4m - 15840 = 1980+1.5m
Rearranging to solve for m
7.9m = 17820
m = 2255.70 = 2300kg to 2sf
