1. Answer: components
A two dimensional vector can be divided into two parts called horizontal component and vertical component.
A three dimensional vector can be divided into three components: one along x-axis, one along y-axis and one along z-axis.
Hence, the vector parts that add up to the resultant are called components.
2. Answer: 5 miles.
The resultant distance along the straight line from the starting point to the end point would be the displacement.
The displacement would be equal to the magnitude of the hypotenuse formed in the right triangle.
Displacement,
3. Answer: Scalar
A scalar quantity has only magnitude. For example, speed and distance are scalar quantities and can be normally added to find the total.
A vector quantity has both magnitude as well as direction. The components are summed according to vector addition rules. For example, velocity, acceleration, force etc.
Answer:
The deceleration is
Explanation:
From the question we are told that
The distance of the car from the crossing is
The speed is
The reaction time of the engineer is
Generally the distance covered during the reaction time is
=>
=>
Generally distance of the car from the crossing after the engineer reacts is
=>
=>
Generally from kinematic equation
Here v is the final velocity of the car which is 0 m/s
So
=>
