physics
a soccer ball with mass 0.420 kg is initially moving with speed 2.00 m/s. a soccer player kicks the ball, exerting a constant force of magnitude 40.0 N in the same direction as the ball's motion. over what distance must the player's foot be in contact with the ball to increase the ball's speed to 6.00 m/s?

Hydraulics: Water is flowing through a pipe
Water is flowing through a pipe having diameter 300mm and 200mm at the bottom and upper end respectively. The intensity of pressure at the bottom end is 24.525 N/cm^2 and the pressure at the upper end is 9.81 N/cm^2. Determine the difference of elevation of the two ends if the rate of flow is 40 liters/sec. Assume no head loss.

Depletion Cost - The Percentage of Depletion Allowance Method
To develop an oil well containing 2,000,000 barrels of oil required an initial investment of PhP 30,000,000.00. In a certain year, 400,000 barrels of oil were produced from this well.
The total gross income of the oil company is PhP 34,000,000.00 for the particular year, and the taxable income after talking all deductions, except for depletion, is PhP 14,100,000.00. Determine the allowable depletion allowance for the year.
differential equation: Determine whether a member of the family can be found that satisfies the initial conditions
The given two-parameter family is a solution of the indicated differential equation on the
interval (−∞,∞). Determine whether a member of the family can be found that satisfies the
initial conditions.
y = c1e^x cos x + c2e^x sin x; y" − 2y' + 2y = 0,
i. y(0) = 1, y'(π) = 0
ii. y(0) = 1, y(π) = −1
