Answer:
Acceleration = Final velocity-initial velocity/time
In m/s^2
a = 40000-0 /10
= 4000m/s
in km/h
a = 40/10÷360
= 1440km/h
Answer:

What is vector?</h3>
- In mathematics and physics, the term "vector" is used informally to describe certain quantities that cannot be described by a single number or by a set of vector space elements.
- In the past, vectors were first used to represent quantities with both a magnitude and a direction, such as displacements, forces, and velocity, in geometry and physics (usually in mechanics). Similar to how distances, masses, and time are represented by real numbers, these quantities are represented by geometric vectors.
- In some circumstances, tuples—finite sequences of numbers with a definite length—are sometimes referred to as vectors.
The two vectors are given as A and B.
As per the question, the two vectors intersect each other perpendicularly
Hence, the angle between them is
The magnitude of the resultant is given as R.
From the parallelogram law of vector addition, the resultant R is calculated as

Question:
Suppose two initial vectors intersect at a right angle and form a resultant vector. The magnitudes of one initial vector, A, and the resultant vector, R, are given. Which formula can be used to find the magnitude of the other initial vector, B?
Option A, B, C, D
Child on a swing, Pendulum, Bow and Arrow, Roller Coaster is mechanical energy being conserved
<u>Explanation:</u>
Mechanical energy is the total of kinetic and potential energy in a thing that is employed to do a job. A conservative force is a power like gravitation or a spring that “bends backward” energy that was conveyed by producing activity. The friction and other non conservative forces, nevertheless, conservation of mechanical energy is surely conserved.
When one stretches or contracts an elastic object, one does act fronting the spring force, and that task finishes up saved as elastic potential energy. Constantly shifting things up and down, producing variations in potential energy is termed as gravitational potential energy.
Here Child on a swing, Pendulum, Bow & Arrow, Roller Coaster in all there is the continuous conversion between gravitational/elastic potential energy and kinetic energy.
