Explanation:
Answer:
<em>The first law states that</em> every planet describes an elliptical path about the sun as a single focus.
<em>The</em><em> </em><em>second</em><em> </em><em>law</em><em> </em><em>states</em><em> </em><em>that</em><em> </em>The line joining the planet to the sun sweeps out equal areas in equal time intervals.
<em>The</em><em> </em><em>third</em><em> </em><em>law</em><em> </em><em>states</em><em> </em><em>that</em><em> </em>The squares of the period of revolution is proportional to the cubes of the mean distance between the planet and the sun
Answer:
16.74 m/s
Explanation:
From the question, the parameters given are:
Height h = 12.2 metres
Initial velocity U = 13.9 m/s
Time t = 1.58 s
The range or distance covered by the ball will be
R = u^2/g
Where g = 9.8 m/s^2
R = 13.9^2/9.8
R = 193.21/9.8
R = 19.72 m
Let first calculate the acceleration by using the formula below
R = Ut + 1/2at^2
Substitute all the parameters into the formula
19.72 = 13.9 × 1.58 - 1/2 × a × 1.58^2
19.72 = 21.962 - 1.2482a
Collect the like terms
-1.2482a = 19.72 - 21.962
- 1.2482a = - 2.242
a = 2.242/1.2482
a = 1.796 m/s^2
Using equation 1 to find the final speed
V = U + at
V = 13.9 + 1.796 × 1.58
V = 13.9 + 2.838
V = 16.74 m/s
Therefore, it hit the ground at speed 16.74 m/s
Answer:
so i believe your answer is abt 1800-2400
Explanation:
According to the Dietary Guidelines for Americans 2010, sedentary teen girls between the ages of 13 and 18 need 1,600 to 1,800 calories per day, while active girls require 2,200 to 2,400 calories each day
Answer:
W = 18.88 J
Explanation:
Given that,
Constant force, F = 11.8 N (in +x direction)
Mass of an object, m = 4.7 kg
The object moves from the origin to the point (1.6i – 4.6j) m
We need to find the work is done by the given force during this displacement. The work done by an object is given by the formula as follows :
So, the work done by the given force is 18.88 J.
