Need this badly today
17. At what speed must a 1000kg car approach a ramp which has a slope and 12m high at the top such that it will just coast to the top. Assume the constant retarding force due to friction, wind, etc. to be 60kg.

Engineering Economy
Juan plans to raise a new building of 1 million. He raise the building by issuing 10%, 20 yr bond that would pay one hundred fifty thousand interest per year an repay the amount of maturity he can least it for Php 140,000 per year. First payment being due one year from now. The building has an expected life of 20 yrs. ignoring effects on income tax, what is the difference between buying the building and leasing it?

Value of a Bond
Value of a Bond
It is defined to be the present worth of all the amounts the bondholder will receive through his possession of the bond.
The bondholder will receive two types of payments which are:
1. Single payment which the owner will receive at the date of maturity of the bond, which is usually equal to the par value of the bond; and
2. The periodic payments for interest on the bond usually it is redeemed by the issuing corporations.
Formula for value of a bond:

DYNAMICS
A balloon rises from the ground with a constant acceleration of 4ft per sec^2. Five seconds later, a stone is thrown vertically up from the launching site. What must be the minimum initial velocity of the stone for it to just touch the balloon? Note that the balloon and stone have the same velocity at contact.

Normal shock wave
1. Consider a NSW with a downstream-upstream temperature ratio of 3.5 what is the mach number upstream and downstream of the shock? Show your solution.
2. The flow just upstream of a NSW is at SSLC and the mach number downstream is 0.6152 determine the pressure, temperature, density, velocity, and the total pressure and temperature. Show your solution
3. The mach number behind of a NSW is 0.4752
What is the mach number in front of the wave and the pressure ratio across the shock? Show your solution.

Acceleration of Riged body (flyweight) with forces
I have a flyweight that rotates about a pin in a cvt clutch.
the flyweight gets its motion from centrifugal force that acts on the center of gravity on the object. i am trying to develop the acceleration equation using kinamatics but am a little rusty. i have developed the force equations but would like help with the acceleration.
