The body falls without initial velocity from a certain height. If the initial height is increased by 4 times, then how many times will the speed increase before hitting the ground?
To calculate the increase in body speed before hitting the ground, we use the ratio: k = Vк2 / Vк1 = √ (2g * h2) / √ (2g * h1).
Ratio of variables: h2 (considered height) = 4h1 (starting height).
Calculation: k = √ (2g * h2) / √ (2g * h1) = √ (2g * 4h1) / √ (2g * h1) = 2 * √ (2g * h1) / √ (2g * h1) = 2 p …
Answer: The speed before hitting should increase 2 times.
