Explanation:
Given that,
The x-component is 8 m/s east and y-component is 14.5 m/s North.
(a) As both x and y components are perpendicular to each other. Their resultant is given by :
(b) Let is the resultant vector. So,
Hence, the resultant is 16.56 m/s and the angle of the resultant vector is 61.11 degrees.
I would say the energy transformation that happens would be potential energy to kinetic energy. Potential energy is the energy possessed by an object when at rest. As you eat a meal, you store potential energy. As you move around, this energy is used and is transformed to the energy of motion which is the kinetic energy.
Ohms law is V = IR
from this we can rearrange so that I or current is the subject
I = V/R
so if both V and R are doubled, we can represent it as such
I = 2V/2R
The 2s will cancel out hence they effect on the current is nil
Answer:
Explanation:
To answer the question, we just need to consider the motion along the horizontal direction.
The component of the initial velocity of the ice skater along the x-direction is:
where u = 2.25 m/s is the initial velocity and is the angle.
The component of the final velocity of the ice skater along the x-direction is
where u = 4.65 m/s is the final velocity and is the angle.
The acceleration along the x-direction is given by
where
t = 120 s is the time
Substituting,
