Answer:
6.77 m/s
Explanation:
Acceleration = Force/mass;
The block is accelerated by 13/6.4 m/s^2 for 2.1s from an initial velocity of 2.5m/s.
Applying the equation of motion:
Vf=Vi + at
Where Vf is the final velocity, Vi is the initial velocity, a is the acceleration and t is the time for which the object accelerates.
<h3>Vf= 2.5 + ((13/6.4)*2.1);</h3>

Answer:
see that the correct one is D
Explanation:
In this problem the satellite is subjected to the universal force of attraction
F = G M m / r²
using Newton's second law with centripetal acceleration you can find the angular velocity of the satellite
F = m a
F = m w² r
G M / r³ = w²
and w = 2π / T
In this case, the satellite is in a two-dimensional movement, where the free fall of the satellite is compensated by the horizontal displacement, for which it is always at a distance from the earth, remaining at the same point.
When reviewing the different statements we see that the correct one isD
Answer:
r = √ x² + y² and θ = tan⁻¹ y / x
Explanation:
The polar coordinates are obtained by transforming the Cartesian coordinates (x y) into others (r tés), for this we use to find r the Pythagorean theorem
r = √ x² + y²
To find teas we use trigonometries
tan θ = y / x
θ = tan⁻¹ y / x
In general the angle can be given in any unit, but the most used in physics is in radians
Answer:
2
a) 109, 111, 113, 115
b) An odd number always follows an even number. So there can't be four consecutive even numbers. 2009, 2011, 2013, 2015 are the next odd numbers between 2008 and 2030.
c) 995, 997, 999, 1001, 1003, 1005, 1007
3
a) The sum of two odd numbers will result in an even number.
b) The sum of two even numbers will result in an even number.
c) The sum of an odd and an even number will result in an odd number.
