Answer:
Explanation:
An object begins from rest and accelerates at a rate of 2.5 meters ... at a rate of +1.6 meters per second' while traveling +5.0 ... Calculate the block's rate of acceleration. 4. Vf² V, ²+2 ad. (12 m/s)?-(Omis) + 2(a)(50m) ... represents the motion of a car during a 6.0 second time interval. ... A cat moves 15 meters east in 5 seconds.
Answer: Two children are riding on a marry-go-round. Child A is at a greater distance from the axis of rotation than child B. Thus, the child A, located at a greater distance from the axis of rotation have a larger tangential speed.
Explanation: To find the correct answer we have to know more about the Angular velocity of a rotating body.
<h3>What is the angular velocity?</h3>
- In rotational motion, the angular velocity ω can be defined as, the change in angular displacement(Ф) per unit time (t).
- It's the revolution per second.
- The angular velocity can be expressed in terms of the tangential velocity as well as the radius of the circular path as,
<h3>
How to solve the question?</h3>
- We know that the expression for the tangential velocity as,
- In the question, for both the child, the value of w will be same. Thus, the only quantity that depends on the tangential velocity will be the distance from the axis of rotation.
- The maximum will the value of V, if the r maximizes.
- Thus, child A with greater distance will have larger tangential speed.
Thus, we can conclude that, child A with greater distance will have larger tangential speed.
