A police cruiser chasing a speeding motorist traveled 60 km south, then 35 km northeast, and finally 50km west.
a) calculate the total displacement of the cruiser
a) calculate the total displacement of the cruiser
thomasrules said:LOL but I did make a diagram...I got the answer from the book just don't know how it was done...the answer is 43km s36w

I got the picture you drew /|
I will choose to use sin theta= Opposite/Hypotenuse
but I don't know the values of O and H
Circular motion is a type of motion where an object moves along a circular path. This means that the object is constantly changing direction, but the distance from the center of the circle remains constant.
In uniform circular motion, the speed of the object remains constant while the direction of motion changes. In non-uniform circular motion, the speed of the object is not constant and can vary throughout the motion.
Centripetal acceleration is the acceleration that keeps an object moving in a circular path. It always points towards the center of the circle and is directly proportional to the square of the object's speed and inversely proportional to the radius of the circle.
Centripetal force is the force that is responsible for keeping an object in circular motion. It is always directed towards the center of the circle and is equal to the product of the mass of the object, its speed, and the radius of the circle.
The period of circular motion is the time it takes for an object to make one complete revolution around the circle. The frequency is the number of revolutions the object makes in one second. The relationship between period and frequency is inverse, meaning that as the period increases, the frequency decreases, and vice versa.
