An Object Is Projected Vertically Upward with an Initial Velocity $\mathcal { v } _ { 0 }$

question 20

Multiple Choice

An object is projected vertically upward with an initial velocity of $\mathcal { v } _ { 0 }$ ft/sec, and its distance $s ( t )$ in feet above the ground after $t$ seconds is given by the formula $s ( t ) = - 16 t ^ { 2 } + v _ { 0 } t$ . If the object hits the ground after $15$ seconds, find its initial velocity $\mathcal { v } _ { 0 }$ in ft/sec.

• A) \(209\) ft/sec
• B) \(226\) ft/sec
• C) \(17\) ft/sec
• D) \(240\) ft/sec
• E) \(256\) ft/sec

Definitions:

Yield to Maturity

The total return anticipated on a bond if the bond is held until it matures, reflecting interest payments and price changes.

Price Yield Curve

A graph that shows the relationship between the yield of bonds and their maturities, illustrating how interest rates affect bond prices.

Convexity

A measure of the curvature in the relationship between bond prices and bond yields that demonstrates how the duration of a bond changes as the interest rate changes.

Modified Duration

A measure that estimates the price sensitivity of a bond to a one percent change in interest rates, adjusting for the changing yield to maturity.
