If jill starts out at 20 m/s, and in 10 s speeds up to 40 m/s, what is her acceleration?
o 3 m/s2
o 200 m/s2
02 m/s2
01 m/s2

Explanation:

The acceleration of an object (or a person, as in this case) is given by

where

v is the final velocity

u is the initial velocity

t is the time interval

In this problem,

u = 20 m/s

v = 40 m/s

t = 10 s

Therefore Jill's acceleration is

The acceleration of Jill is if he starts out at the velocity 20 m/s and in 10 s speeds up to 40 m/s.

From given, we came to know that the Jill starts out at 20 m/s, and in 10 s speeds up to 40 m/s, to find acceleration of Jill, we know that acceleration is ratio of velocity to time change.

The acceleration is given by the formula:

We know that change in velocity as 20 m/s to 40.0 m/s and change time as 10 s.

Thus, acceleration of Jill will be

science is a systematic and logical approach to discovering how things in the universe work. true to this definition, science aims for measurable results through testing and analysis. science is based on fact, not opinion or preferences. the process of science is designed to challenge ideas through research.

explanation:

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.
