12. A solar-thermal power plant (Tonapah, for example) might cost $2B to build and operate over its 20 year lifetime. Assume it generates 100 MW for 8 hours a day; assume it is always sunny during the days:
a) How much must be charged wholesale for generation of this electricity, just to cover that initial cost?
Please compute the cost in $/kW-hr, which is the wholesale consumer cost that is quoted. Note for a
natural gas power plant, this wholesale cost is $0.05/kW-hr, approximately. Make any simplifying econ.
assumptions postulates as are helpful.

positive reinforcement? ?

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
