An object dropped from a cliff falls with a constant acceleration of 1...
Given
- Acceleration = 10m/s^2 (constant)
- Time = 5s (after it was dropped)
- Initial Velocity = 0m/s (since it was dropped from rest)
Formula
- Final Velocity (v) = Initial Velocity (u) + (Acceleration (a) * Time (t))
Solution
Using the formula, we can calculate the final velocity:
- v = u + at
- v = 0 + (10 x 5)
- v = 50 m/s
Answer
The speed of the object 5 seconds after it was dropped is 50 m/s.
Explanation
When an object is dropped from a height, it experiences a constant acceleration due to gravity. This acceleration is always equal to 9.8 m/s^2 (or 10 m/s^2, rounded off). This means that every second, the object's velocity increases by 10 m/s. So, after 5 seconds, the object's velocity would have increased by 50 m/s (10 x 5 = 50). Since the object was dropped from rest, its initial velocity is 0 m/s. Therefore, the final velocity after 5 seconds is 50 m/s.
