Which motion maps show an object in uniform circular motion? Check all that apply. V W X Y
2 answers:
Explanation:
In this case we need to say that out of the attached figure which shows that the object is in uniform circular motion.
When and object moves in a circular path, its motion is called circular motion. In this type of motion, the speed of the object remains constant while its position changes i.e. its velocity changes.
Out of attached options, V shows circular motion, as the object is position continuously. W and Y are similar cases.
So, V, X and Y shows the circular motion of the object. Hence, this is the required solution.

Answer:
Explanation:
We are asked to find the cyclist's initial velocity. We are given the acceleration, final velocity, and time, so we will use the following kinematic equation.
The cyclist is acceleration at 1.2 meters per second squared. After 10 seconds, the velocity is 16 meters per second.
= 16 m/s
- a= 1.2 m/s²
- t= 10 s
Substitute the values into the formula.
Multiply.
We are solving for the initial velocity, so we must isolate the variable . Subtract 12 meters per second from both sides of the equation.
The cyclist's initial velocity is <u>4 meters per second.</u>
