One ship, sailing east with a speed of 7.5 m/s, passes a certain point at 8 AmM; and a second ship sailing north at the same speed, passed the same point at 9.30 A. M. At what time are they
closest together and what is the distance between them then? [Ans: 8.45 A. M., 28.6 km]

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.

magnets not strong enough
