Answer:
3. 3.5 s
Explanation:
The position of traveller A is given by the equation:

where
is the acceleration of A
t is the time measured from when A started the motion
The position of traveller B instead is given by

where a (acceleration) is the same as traveller A, and

is B's initial velocity. We can verify that the formula is correct by substituting t=2, and we get
, which means that B starts its motion 2 seconds later.
Traveller B overtakes traveller A when the two positions are the same, so:

The relationship between speed of a wave w, frequency f and wavelength

is

For the wave of our problem,

and f=60 Hz, so its speed is
Answer:
what is the direction of the sum of these two vectors?
