Answer:

<h2>10890 J</h2>

Explanation:

The kinetic energy of an object can be found by using the formula

k =  \frac{1}{2} m {v}^{2}  \\

m is the mass

v is the velocity

From the question we have

k =  \frac{1}{2}  \times 45 \times  {22}^{2}  \\  =  \frac{1}{2}  \times 45 \times 484 \\  = 45 \times 242 \\  = 10890

We have the final answer as

<h3>10890 J</h3>

Hope this helps you

Lady_Fox [76]

The time t it takes for the key to fall 44 m is

44\,\mathrm m=\dfrac12\left(9.8\,\dfrac{\mathrm m}{\mathrm s^2}\right)t^2\implies t=3.0\,\mathrm s

(notice I'm taking the downward direction to be positive)

The boat, moving at a presumably constant speed, then has 3.0 s to travel 19 m to the point of impact, which means its speed must be

v=\dfrac{19\,\mathrm m}{3.0\,\mathrm s}=6.3\,\dfrac{\mathrm m}{\mathrm s}

Name one similarity and one difference between a set and a bump in volleyball??
kotykmax [81]
Bump: Bumping the ball means a player uses their forearms to pass the ball to a teammate or to hit the ball back over the net to the other team. Set: Setting the ball means a player positions the ball in a way that lets a teammate spike it over the net.
