3.00 is my correct answer this is what my teacher told me.thanks
Answer:
Distance travelled: 20meters
Displacement: 10 meters.
Explanation:
In geometry and mechanics, a displacement is a vector whose length is the shortest distance from the initial to the final position of a point P undergoing motion. It quantifies both the distance and direction of the net or total motion along a straight line from the initial position to the final position of the point trajectory. A displacement may be identified with the translation that maps the initial position to the final position.
<u>Answer:</u>
h = 4.25 m
<u>Explanation:</u>
,
where m is the mass, g is acceleration of gravity, and h is height of object.
In our case, m = 1.2 kg, g = 9.8m/s², and gpe = 50 J.
50 = 1.2 x 9.8 x h
h = 50 / (1.2 x 9.8)
h = 4.25 m
The average distance between the Earth and the Sun is 149.60 million km (92.96 million mi), and one complete orbit takes 365.256 days (1 sidereal year), during which time Earth has traveled 940 million km<span> (584 million mi).</span>
157.5J
KE=1/2 mv^2
KE= 1/2(35kg)(3m/s)^2
KE=(17.5kg)(9m^2/s^2)
KE= 157.5J
