Small rockets are used to make tiny adjustments in the speed of satellites. One such rocket has a thrust of 50.0 N. If it is fired to change the velocity of a 75,000-kg spacecraft by 45 cm/s, how long should it be fired?

answer: a) y=-8x+5

a) m= -8

b) m= -2

c) m= 7

d) m= 6

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary 

wavelength divides in half and speed stays the same.
