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?

Submitted by eaomar on

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.

I've been trying to solve the following question for 2 days now and i can't seem to be able to. can someone help me please ?

For the beam shown in Figure 3, the support at A is fully fixed. The beam is tapered however you may consider it to be a beam of 3 varying sections.

Take:
Beam A to B as having 3 times the I value of beam D to end, Beam B to D as having 1.5 times the I value of beam D to end and Beam D to end is 310 UB 46.2 with I = 100 x 106 mm4. Tip: this may be easier to solve using superposition.

A structural steel column with Fy = 250 MPa
having an unbraced length of 3m is to carry a total axial load of 1800 kN. Which of the following sections is most economical (lightest ) for the given loads. The comumn is hinged at both ends.
Section A: Area = 13,800mm2 Ix= 293.63 x106mm4Iy= 67.59 x 106mm4
SectionB: Area = 11,550 mm2 Ix=177.04 x 106mm4Iy=39.14x 106mm4
