To understand how the provided data substantiates Newton's second law of motion,
Given Data:
- Mass of the car:
kg - Initial velocity of the car:
m/s - Final velocity of the car (stop):
m/s - Force applied and time taken to stop in two trials.
Calculating Deceleration:
Using the kinematic equation:
Trial 1 Calculations:
- Force applied:
N - Time required to stop:
s - Acceleration:
- Using
: (The negative sign indicates the force is in the opposite direction of motion.)
Trial 2 Calculations:
- Force applied:
N - Time required to stop:
s - Acceleration:
- Using
:
Conclusion:
Both trials show that the applied force is consistent with Newton's second law of motion (
Thus, the information substantiates the equation
