3. during liftoff, a space shuttle accelerated to a speed of 862 m/s in 75 seconds. what was the
average acceleration of the astronauts in the space shuttle with respect to the shuttle during
liftoft?
a 0 m/s2
b. 9.8 m/s2
c. 11.5 m/s2
d. 19.6 m/s2
motion and momentum (copy)

11.493 or 11.5

Step-by-step explanation:

by dividing speed by time. 862/75

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

answer is (b.
