The rocket-driven sled Sonic Wind No. 2, used for investigating the physiological effects of large accelerations, runs on a straight, level track that is 1080 m long. Starting from rest, it can reach a speed of 1590 km/h in 1.70 seconds.

What is the acceleration during this time?

Express your answer in meters per second squared.

Answer :

The acceleration during this time is 279 m/s², indicating a significant rate of change in velocity for the rocket-driven sled.

Acceleration measures the change in velocity per unit of time. In this case, we have a rocket-driven sled starting from rest and reaching a final velocity of 1590 km/h in 1.70 seconds. To calculate the acceleration, we use the formula: acceleration = (final velocity - initial velocity) / time. Converting the final velocity to m/s, we find that the acceleration during this time is approximately 279 m/s².

The acceleration of 279 m/s² indicates that the rocket-driven sled is experiencing a significant rate of change in velocity. It is important to note that this acceleration value only applies to the given time interval of 1.70 seconds. Acceleration is a key parameter in understanding the impact of forces on objects and is crucial for studying the physiological effects of large accelerations.

Acceleration is a vector quantity that includes both magnitude and direction. It represents how fast an object's velocity is changing. Positive acceleration indicates an increase in velocity, while negative acceleration (or deceleration) represents a decrease in velocity. Acceleration is influenced by external forces acting on an object, such as propulsion systems in the case of the rocket-driven sled.

Acceleration plays a vital role in various scientific and engineering fields. It is used to study the motion of objects, analyze the effects of forces on bodies, and design transportation systems, among other applications. Understanding acceleration helps scientists and engineers ensure the safety and efficiency of various systems, such as vehicles, aircraft, and amusement park rides.
