Final answer:
The rocket sled's initial acceleration can be calculated using the equation of motion by substituting the given values for thrust, force of friction, and mass.
Step-by-step explanation:
The rocket sled's initial acceleration can be determined using the equation of motion:
acceleration = (thrust - force of friction) / mass
- Substitute the given values into the equation: acceleration = (2.4 × 10^4 N - 650 N) / 2.1 × 10^3 kg
- Calculate the acceleration: acceleration = (2.4 × 10^4 N - 650 N) / 2.1 × 10^3 kg = 10.9 m/s²
- Therefore, the rocket sled's initial acceleration is 10.9 m/s².
