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

the following is queen elizabeth’s purposes:

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
