a) . t= v/a = 334/10 = 33.4 sec
b) t= 11200/10 = 1120 sec = 18.67 min .
c) 10% of speed of light = 3x107 m/s
time = 3x107/10 = 3x106 sec
= 34.7 days .

From the college records, It was always known that 10% of the students who take Eng. 304 course would receive a letter grade of an "A", among the lo sections of the same course which usually total to 350 students, . Using the normal approximation concept, please find the following: 1. Probability that at least 40 students will receive A's? 2. Probability that at most 300 students will receive grades other than A's? 3. Expected number of students and the...

Goldberg's sleigh currently runs at 203mph, but he needs it to reach 400mph with all the packages he has to deliver. If Goldberg is delivering presents at an altitude of 5,813.6ft, with the same drag and weight of a 2019 Challenger SRT® Hellcat Redeye, how much HP would he need to reach 400 mph? Pro Tips 100% driveline efficiency P (air density) at 5813.6 ft = .0019 slug/ft^3 A (Area of Challenger front end) = 26.72 ft^2 C(d) (Coefficient of...
