The vertical velocity of the car at the given position and time is 4.905 m/s.
The given parameters:
- Initial angular velocity,
= 6.3 rad/s - Time of motion, t = 0.25 s
- Vertical displacement, y = 0.75 m
- Angular acceleration,

<h3>What is vertical velocity?</h3>
- This is the linear velocity of an object in a vertical direction.
The angular velocity of an object in a circular motion is given as;

The vertical velocity of the car at the given position and time is calculated as follows;

Thus, the vertical velocity of the car at the given position and time is 4.905 m/s.

The answer to your question is the Pension Plan
The final temperature on the block is 25 degrees.
Heat is a form of energy. This question shows that energy is transferred from the acetone to the metal block.
Data given;
- M1 = 3.33g
- T1 = 25 degrees
- M2 = 44g
- T2 = 25 degree
- C1 = 124.5 J mol K
- C2 = 0.89 J/g K
<h3>Heat Transfer</h3>
Applying the principles of heat transfer,
Heat loss = Heat gain

From the calculation above, the final temperature on the block is 25 degrees.
