i put in (30cos45)(5.2s) but i got 82m instead of 92 m
Vectors in physics are quantities that have both magnitude (size) and direction. They are represented by arrows, where the length of the arrow corresponds to the magnitude of the vector, and the direction of the arrow indicates the direction in which the vector is pointing.
Vectors are used in many areas of physics, such as mechanics, electromagnetism, and thermodynamics. They are used to describe and analyze the motion of objects, forces acting on objects, and other physical quantities.
A scalar is a quantity that has only magnitude, whereas a vector has both magnitude and direction. Examples of scalars include temperature, time, and speed, while examples of vectors include displacement, velocity, and force.
To add or subtract vectors, you can use the graphical method or the component method. In the graphical method, you draw the vectors to scale and use the parallelogram rule or the head-to-tail method to find the resultant vector. In the component method, you break the vectors down into their x and y components and then add or subtract the components separately.
Yes, vectors can be multiplied in two ways: scalar multiplication and vector multiplication. Scalar multiplication involves multiplying a vector by a scalar (a number), which changes the magnitude of the vector. Vector multiplication, also known as the dot product or cross product, involves multiplying two vectors together to produce a scalar or vector result, respectively.
