相关例题：
Question: A student drops a ball from a height of 2 meters. Assuming that the ball lands with the same velocity it had when it left the hand of the student, what was the initial velocity of the ball?
Answer: To find the initial velocity of the ball, we need to know the height from which it was dropped and the distance it fell.
Assuming that the ball fell freely for a certain distance before hitting the ground, we can calculate its velocity at that point using the formula for free fall acceleration:
v² = 2gh
where v is the velocity of the ball, h is the height from which it was dropped, and g is the acceleration due to gravity.
If we know the height and velocity at this point, we can calculate the initial velocity of the ball by subtracting the height from which it was dropped from its final velocity.
Example:
A student drops a ball from a height of 2 meters. The ball lands with a velocity of 10 m/s. Calculate the initial velocity of the ball.
Solution:
1. Calculate the velocity at the point where the ball hits the ground using the formula for free fall acceleration:
v² = 2g(2m) = 40 m²/s²
2. Subtracting 2 meters from this velocity gives us the final velocity of the ball:
v = 6 m/s
3. The initial velocity of the ball is then 4 m/s, which is 2 meters higher than its final velocity.
