Question:

What is the role of the secondary market?

Inactive
Justin F.

The secondary market provides liquidity for investors to buy or sell investments. This provides greater value for investors since they can more quickly convert these assets to cash if necessary.

Question:

If a ball is thrown up straight up into the air at a rate of 25 m/s how long will it take for it to return to the ground? How high will it go?

Inactive
Justin F.

Using the formula Velocity = Velocity(Initial) - Acceleration*Time Velocity = 0 Velocity(I) = 25 m/s Acceleration = -9.8 m/s^2 (due to gravity) Time then equals 2.55 seconds [Rounded] Using the formula Height = (Velocity * Time) + [(Acceleration/2) * (Time)^2] Velocity = 25 m/s Time = 2.55/2 = 1.275 seconds (Divided by 2 because height is calculated at peak, which is half way through the time the ball is in the air) Acceleration = -9.8 m/s^2 (due to gravity) Height then equals 23.91 meters
