- 10. A rocket ship has a mass of 1.50 x 105 kg. Its relativistic momentum is 3.00 x 1012 kg•m/s. How fast is the rocket ship traveling?
- How fast would a meterstick be moving so that its length will be observed to shrink to half its original length?
- How much work must be done to a proton to accelerate it from rest to 0.998c.
- A person on Earth observes a space ship approaching from the right with a velocity of 0.75c and a rocket ship approaching from the left at 0.50c. What is the relative velocity of the two ships as measured by a passenger in each of them?

On an average 5% of the population in an area suffers from Diabetes. What is the probability that out of 7 persons chosen at random from this area with less than and equals to three suffer from the disease
(1) Write a program that will ask for a price.
(2) If the price is greater than 1000, compute a 10% discount from the original price. Display the computed discount.
(3) If not, just display the original price.
