Find the magnitude of this vector:

Physics
1 answer:
xeze [42]1 year ago
3 0

Answer: = 25. 5 m

Explanation:

  • 2-D vectors can be solved using the Pythagorean theorem:  
  • a^{2} +b^{2} =c^{2}
  • The hypotenuse, or longest side is not given and that is what must be solved for
  • Direction can be omitted as the question only asks for magnitude
  • Magnitude: is the distance or quantity in which an object moves during motion

Solve for C using Pythagorean theorem:

1. \sqrt{a^{2}+b^{2}  }=c

2.  \sqrt{22.2 m ^{2} +12.6m^{2} } =c

3. 25.52646 m= c

  • round to lowest number of significant digits  when dividing and multiplying
  • rounded to 3 significant digits

∴ Magnitude of the vector is 25.5 m

A ball is released from a hot air balloon moving downward with a velocity of -10.0 meters/second and a height of 1,000 meters. H
Nikolay [14]
Here, ball is released... and it is in free fall means with zero initial velocity.

We know, s = ut + 1/2 at²
Here, s = 1000 m
u = 0
a = 10 m/s2

Substitute their values, 
1000 = 0 + 1/2 * 10 * t²
2000 = 10 * t²
t² = 2000 /10
t = √200
t = 14.14 s

In short, Your Answer would be 14.14 seconds

Hope this helps!
