Velocity Problem? Physics?

Question

you are travelling at 51km/hr and you increase your speed by 1 ft/s what is your final velocity?

Answer 1

Faster than before!

Answer 2

51 km/hr = 167,322.83 ft/3600 sec

+ 1ft/sec

=167,323.83ft/3600sec

reduced: 46.48ft/sec

Answer 3

There is an error in the first answer...

51 km/hr = 46.5 m/sec

add 1 and get...

47.5 m/sec (or to show respect for significant figures...47 m/sec) or 32.4 miles/hr or 14.5 m/sec

or in better units...

3.32 furlongs/sec = 4.02 E6 furlongs/fortnight

Answer 4

Your question as stated can only be infinity.

No parameters are given, No location such as inside the envelope of Earth or celestrial bodies within a Solar system.

As stated a 51Km/hr is a measured amount, by adding a 1 foot per second increase will set off a chain reaction that will multiply until another force intervenes.
