a cow sees a break in the fence and runs for her freedom. as she passes through the fence her speed gose from 3 m/s to 10 m/s in a matter of 90 seconds. calculate her acceleration. show your work and include correct units for full credit. round your answer to proper significant figures

0.078m/s2

Explanation:

From the question given, we obtained the following information:

V = 10 m/s

U = 3 m/s

t = 90secs

a =?

Recall,

a = (V — U) / t

a = (10 — 3) / 90

a = 7/90

a = 0.078m/s2

The acceration of the cow is 0.078m/s2

The answer to your question is a = 0.08 m/s²

Explanation:

This is a problem of linear motion where the speed changes during over time so, there is an acceleration.

Data

vo = 3 m/s

vf = 10 m/s

t = 90 s

a = ?

Formula

a = (vf - vo) t

Substitution

a = (10 - 3)/90

Simplification

a = 7/90

Result

a = 0.08 m/s²
