Question

What is the acceleration of the race car that moves at a constant velocity of 300km/hr?

Answer 1

since the velocity of the car is constant.
therefore
acceleration of the car = 0 m/s^2

Answer 2

Answer:

Given

AOBC is a rectangle

It has 3 vertices, they are A(0 , 3) O (0 , 0) and B (5 , 0)

Required to find

Length of the diagonal.

Solution

\sf ab = \sqrt{ { (x_{2} - { x_{1})} }^{2} } + (y_{2} - { y_{1})}^{2}ab=

Note

•You can find diagonal if you have the width and the height.

•A recrangle has 2 diagonals , each one is line segment drawn between the opposite vertices of the rectangle.

•Diagonals are always congruent
