i wanna learn a little bit of physics so if anyone could teach me a thing or two it would be much appreciated
2 answers:
<em>Things I would work on for starting are these Basic principles of physics </em>
<em>1. Newton's laws of motion. </em>
<em>2. Mass, force, and weight (Mass versus weight) </em>
<em>3. Momentum and conservation of energy. </em>
<em>4. Gravity, theories of gravity. </em>
<em>5. Energy, work, and their relationship. </em>
<em>6. Motion, position, and energy.</em>
<em>Apologies if this wasn't what you were searching for. (；′⌒`)</em>

Answer:
a.14 s
b.70 s
Explanation:
a.Let the sidewalk moving in positive x- direction.
Speed of sidewalk relative to ground=
Speed of women relative to sidewalk=v=1.5m/s
The speed of women relative to the ground
Distance=35 m
Time=
Using the formula
Time taken by women to reach the opposite end if she walks in the same direction the sidewalk is moving=
b.If she gets on at the end opposite the end in part (a)
Then, we take displacement negative.
Speed of sidewalk relative to ground=
Speed of women relative to sidewalk=v=-1.5 m/s
The speed of women relative to the ground=
Time=
Hence, the women takes 70 s to reach the opposite end if she walks in the opposite direction the sidewalk is moving.
