Please help me I am being timed!! Question: Two cars leave the Sacramento airport at 8:00 a. m. traveling south to Huntington Beach on Interstate 5. Car A travels at a velocity of 86 km/hour and arrives at Huntington Beach at 4:00 p. m. Car B travels at a velocity of 75 km/hour. How long after car A arrives, will car B arrive at the same destination?

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.

(75°f − 32) × 5/9 = 23.889°c

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
