Aroller coaster car rapidly picks up speed as it rolls down a slope. and it starts down the slope, its speed is 4 m/s. but 3 seconds later, at the bottom of the slope, its speed is 22m/s what is the acceleration?

I hope this helps.

a=(V2-V1)/t

a=(22-4)/3

A=18/3

A=6m/s/s

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.

a. is -1.8

b. 2.236068

c. 2.3333333333333333333

d.   is 3

i hope that ! =)

overcharge is the right answer system
