A skateboarder has an initial velocity of 3 m/s West and comes to a stop in 2 seconds. What is the skateboarder's
acceleration? (Remember...final velocity is stopped.)

FV- 0 m/s

IV- 3 m/s

t- 2 sec

A= FV-IV/t

A= 0-3/2

a= -1.5 m/s²

Explanation:

FV- Final Velocity -> m/s

IV- Initial Velocity -> m/s

A- Acceleration -> m/s²

t- time -> seconds

its 42

i say its d?

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
