A skier traveling 11.0 m/s reaches the foot of a steady upward 19° incline and
glides 15 m up along this slope before coming to rest. What was the average
coefficient of friction? (use conservation of energy method or work energy
theorem)
In a common test for cardiac function (the “stress test”), the patient walks on an
inclined treadmill. Estimate the power required from a 75-kg patient when the
treadmill is sloping at an angle of 12° and the velocity is 3.1 km/h.
A 65.0-kg runner has a speed of 5.20 m/s at one instant during a long-distance
event. (a) What is the runner’s kinetic energy at this instant? (b) How much net
work is required to double his speed?
The force F = i + 3j + 2k acts at the point (1, 1, 1). (a) Find the torque of the force about the point (2, −1, 5). Careful! The vector r goes from (2, −1, 5) to (1, 1, 1)
Guessing numbers
Rahul is playing a guessing number game with computer . the objective of the game is to guess the number that computer think . A guess is "correct" when the guess exactly matches the computer number. After each guess by Rahul, the computer will give a score comprising black & white coins:
Black coins = guessed digit is present in the computer's number and in same position
white coins = guessed digit is present in the computer's number and in another position
your task is to find out the number of black coins and number of white coins
Input:
The first line of input contains two space-separated integers
denoting the Rahul's Guess and the computer's Number.
Output:
The output should be a string denoting the number of Black coins and the number of White coins in the format as shown in the same output.
sample output:
given rahul=1423, computer=1234
so the output should be "blacks : 1 whites : 3 "
sample input2;
1423 5678
blacks : 0 whites : 0

b) ∀x(x ≤ 2)
c) ∃x(x ≥ 4)
d) ∃x(x < 0)
e) ∀x((x < −1) ∨ (x > 2))
f ) ∃x((x < 4) ∨ (x > 7))

Mrs oli plans to select 360 grade eleven students obtained from the population. The selected respondents has an average height of 170 cm and a sample standard deviation of 25 cm. What is the 95% confidence interval of all the student's heights?
The function Power, which raises the integer number x to the power n, can be defined recursively as follows: Power(x, n) = 1 for n = 0 Power(x, n) = x * Power(x, n-1) for n > 0 (i) Using the above definition write the recursive function Power(x, n) in C. (ii) Rewrite the recursive function Power(x, n) in an iterative form. (iii) Write the main function and test the above written functions. Note: You can write one program and test the functions or you may write two separate programs for each part (i) and (ii).
