A rocket car accelerates 4.5 m/s squared over 6.00 s to reach the freeway speed at the end of an entrance ramp. if the cars final speed is 75 m/s, what was its initial speed on it begin accelerating?

Use the definition of average acceleration:

Then

answer: 2 and 1

step-by-step explanation: got this question

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
