Which category has the highest percentage for watching TV?

Lewis Hamilton realized he was late to his race and started running towards the track. As he approached the stairs down to the pit, he grabs for his keys, fumbles them and gives them a downward (vertical only) velocity of 4.9 m/s.  The keys fall from a height of 9.8 m straight down before they hit the ground below.  How long did they take to hit the ground??

If the displacement x of an object is related to its velocity v according to the relationship x=Av, where A is a constant, what are the units of the constant A to ensure the displacement has the correct units??

Which activity do you personally prefer: watching TV or playing video games? Why?

An object is initially moving in the  direction when a force causes it to move in the  direction.  In which quadrant does the velocity vector point after some time moving in the new direction??  That is, the first motion was westward and the second motion is now northward
