Question

Physics Freefall Name 1. You decide to drop a penny from the top of the hotel in New York. It hits a tourist in the head at 32 m/s. How far did the penny fall

Answer 1

Answer:

h = 52.24 m

Explanation:

Given that,

A penny is dropped from the top of the hotel in New York. It hits a tourist in the head at 32 m/s.

Let it falls at a height of h.

We can find the value of h using the conservation of energy such that,

$\dfrac{1}{2}mv^2=mgh\\\\h=\dfrac{v^2}{2g}\\\\h=\dfrac{(32)^2}{2\times 9.8}\\\\h=52.24\ m$

So, it will fall at a distance of 52.24 m.
