Chapter 03, Problem 15

A skateboarder shoots off a ramp with a velocity of 6.0 m/s, directed at an angle of 52° above the horizontal. The end of the ramp is 1.4 m above the ground. Let the x axis be parallel to the ground, the +y direction be vertically upward, and take as the origin the point on the ground directly below the top of the ramp. (a) How high above the ground is the highest point that the skateboarder reaches? (b) When the skateboarder reaches the highest point, how far is this point horizontally from the end of the ramp?

You have been taught that in order to expect higher returns, you need to accept increased risk. In describing this concept, what is the correct ranking of asset securities from probable “least market-price volatility, lowest expected return” to probable “highest market-price volatility, highest expected return:”

(2) Long-term Treasury/Sovereign Bonds

(3) Preferred Stock portfolio,

(4) Emerging-market mutual fund,

(5) Money market fund.

Suppose the​ risk-free interest rate is 5%​, and the stock market will return either be +21% or −10% each​ year, with each outcome equally likely. Compare the following two investment​ strategies: (1) invest for one year in the​ risk-free investment, and one year in the​ market, or​ (2) invest for both years in the market.

a. Which strategy has the highest expected final​ payoff?

b. Which strategy has the highest standard deviation for the final​ payoff?

c. Does holding stocks for a longer period decrease your​ risk?
