Assume that an intercontinental ballistic missile goes from rest to a suborbital speed of 6.50 km/s in 60.0 s (the actual speed and time are classified). What is its average acceleration in $\mathrm{m} / \mathrm{s}^{2}$ and in multiples of $g\left(9.80 \mathrm{m} / \mathrm{s}^{2}\right) ?$

Key Concepts

Average Acceleration

Average acceleration is a measure of how much the velocity of an object changes per unit time. It is calculated by dividing the change in velocity by the time interval over which the change occurs. This concept is fundamental in kinematics and allows us to understand how quickly an object's speed is increasing or decreasing.

Unit Conversion

Unit conversion is the process of converting measurements from one unit system to another to maintain consistency and accuracy in calculations. In problems involving velocity or acceleration, it is essential to ensure that all quantities are expressed in compatible units, such as converting kilometers per second to meters per second.

Gravitational Acceleration

Gravitational acceleration, commonly denoted by g, is the acceleration due to Earth's gravity at its surface. Its standard value is approximately 9.80 m/s². Expressing accelerations in multiples of g provides a meaningful perspective on the magnitude of acceleration in a context that is relatable to everyday experiences of gravitational force.
