Aroller coaster car rapidly picks up speed as it rolls down the slope as it starts downslope its speed is 4 miles per second but 3 seconds later at the bottom of the slope its speed is 22 miles per second what is the average acceleration? a.-6m/sb.7.33m/sc.6m/s

Step-by-step explanation:

a =

a = =

Hope this helped!

x=6 m/s/

Step-by-step

eAccel = Vf - Vi

t x=22 m/s – 4 m/s

3 s

Accel=x

Vf=22 m/s x=18 m/s

Vi=4 m/s 3 s

t=3 s

don't report but were is the digram

step-by-step explanation:

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches
