If Jessica can accelerate at a rate of 5.0 m/s^2, how long will it take for her to reach a speed of 30.0 m/s?

( I need as much detail as possible, I am completely lost please explain)

**drwls**, Tuesday, January 29, 2008 at 12:40pmTo go from 20.0 to 30.0 m/s, that is a velocity change of 10.0 m/s.

From the definition of acceleration,

a = (velocity change)/(time required)

In this case you know that a = 5.0 m/s^2, so

time = (10.0 m/s)/(5.0 m/s^2)

= 2.0 seconds
