a car goes from 15 m/s to 95 m/s in 9 seconds. what is the acceleration? (write your answer in 3 significant figures)
Answer
Explanation:
Step1: Identify the formula for acceleration
The formula for acceleration (a=\frac{v - u}{t}), where (v) is the final velocity, (u) is the initial velocity, and (t) is the time.
Step2: Substitute the given values into the formula
Given (u = 15\space m/s), (v=95\space m/s), and (t = 9\space s). [a=\frac{95 - 15}{9}=\frac{80}{9}]
Step3: Calculate the value
(\frac{80}{9}\approx8.89\space m/s^{2})
Answer:
(8.89\space m/s^{2})
