Suppose you increase your walking speed from 1m/s to 3m/s in a period of 1s. What is your acceleration?
a:2m/s
b:5m/s
c:4m/s
d:3m/s
To find the acceleration, we can use the formula:
acceleration = (final velocity - initial velocity) / time
Given:
Initial velocity (u) = 1 m/s
Final velocity (v) = 3 m/s
Time (t) = 1 s
Using the formula, we can substitute the given values:
acceleration = (3 m/s - 1 m/s) / 1s
acceleration = 2 m/s
Therefore, the acceleration is 2m/s.
So, the answer is a: 2m/s.
To find the acceleration, we can use the formula:
acceleration = (final velocity - initial velocity) / time
Given:
Initial velocity (u) = 1 m/s
Final velocity (v) = 3 m/s
Time (t) = 1 s
Substituting these values into the formula, we get:
acceleration = (3 - 1) / 1
acceleration = 2 / 1
acceleration = 2 m/s²
Therefore, the acceleration is 2 m/s².
The correct answer is option: a) 2m/s.
