Final answer:
To calculate the truck's rate of acceleration, use the formula a = (v_f - v_i) / t. The truck accelerates from 7.0 m/s to 15.0 m/s in 1.5 seconds, yielding an acceleration of 5.33 m/s².
Step-by-step explanation:
The student has asked how to calculate the truck's rate of acceleration when it accelerates from 7.0 meters per second to 15.0 meters per second in 1.5 seconds. To find the acceleration, we can use the formula:
a = (v_f - v_i) / t
Where a is acceleration, v_f is the final velocity, v_i is the initial velocity, and t is time. In this case:
a = (15.0 m/s - 7.0 m/s) / 1.5 s
a = 8.0 m/s² / 1.5 s
a = 5.33 m/s²
Therefore, the truck's acceleration is 5.33 meters per second squared.
