During the 2004 Olympic Games, a shot putter threw a shot put with a speed of 12.1 m/s at an angle of 43.7° above the horizontal. She released the shot put from a height of 2.07 m above the ground.

a) How far did the shot put travel in the horizontal direction?

b) How long was it until the shot put hit the ground?

Solutions

Expert Solution

This is a Projectile Motion Which are Pretty Standard.

The First Step in Projectile Motion is to Divide Velocity in to x,y Components.

Now we have to Take our velocity componrnt which will solve the given question

a)in here we need to use x component ,observe that we dont have any Horizontal Forces acting on shot put.

Hence Horizontal Distance = V*t =

where t is the total time travelled.

b)in projectile motion we have a direct Derivation for Flight time which is

But we also have to cover 2.07 m

Using

Solving For t = 0.21940338695453243 sec

Total Time = 1.706 + 0.21940338695453243 = 1.92540338695 sec===>Answer B

During a fireworks display, a shell is shot into the air with an initial speed of 91.55 m/s at an angle of theta degrees above the horizontal. The fuse is timed to 8.21 seconds for the shell just as it reaches its highest point above the ground. If the horizontal displacement of the shell is 149.68 meters when it explodes, what is the height (in unit of meters) when the shell explodes? You must use g = 9.8 m/s2.

Suppose that a city’s demand for hosting an Olympic Games is described by the demand curve PD = 900 – 20Q, where Q is the number of Olympic events and PD is measured in millions of dollars. (For example, to host 10 Olympic events, the city would be willing to pay $700 million.) The International Olympic Committee’s (IOC’s) marginal revenue from putting on Q events is MR = 900 – 40Q. The IOC’s marginal cost of putting on Q events...
