Analyze the motion of a toy car using ticker tape data, calculating initial velocity, final velocity, and acceleration.

The distance of the first segment (A) is $0.02 \text{ m}$.
The time interval for each segment is $0.02 \text{ s}$.

The initial velocity is $\boxed{1.0 \text{ m/s}}$.

b) ii) What is the final velocity, v, of the toy car?

The distance of the last segment (B) is $0.06 \text{ m}$.
The time interval for each segment is $0.02 \text{ s}$.

The final velocity is $\boxed{3.0 \text{ m/s}}$.

c) Determine the acceleration of the toy car over the measured portion.

There are 5 intervals shown on the tape. The time between the midpoint of the first interval and the midpoint of the fifth interval is $(5-1) \times \text{time interval}$.

The acceleration is $\boxed{25 \text{ m/s}^2}$.

6. Thermometer Calibration

a) Give the name and values of the temperatures A and B in degree Celsius.

• Temperature A: This represents the upper fixed point of the thermometer, which is the temperature of pure boiling water at standard atmospheric pressure. Its value is $\boxed{100^\circ \text{C}}$.
• Temperature B: This represents the lower fixed point of the thermometer, which is the temperature of pure melting ice at standard atmospheric pressure. Its value is $\boxed{0^\
