Two cars travel along a straight road. When a stopwatch reads t=0.00h, car A is at position 24.0km moving at a constant 48.0km/h. Later, when the watch reads t=1.00h, car B is at position 0.00km moving at 74.0km/h.
a) What will the watch read when car B passes car A (in hours)?
b) At what position will the passing occur (in km)?
c) when the cars pass, how long will it have been since car A was at the reference point (in hours)
2) Explain how to correctly use an analog measuring device (such as a meter stick) including determining the least count and how many digits to record.
Please help. This is really important and you need to show your work..
The answers for 1 should turn out to be :
a) 3.77h
b) 205km
c)4.77h
You don't have to answer all of it , part of it is fine , but if you do all of it , thanks so so so much .
