Answer:
-34.3m/s
Explanation:
first lets find the time befor it hit the ground by using free fall equation and we know we use that in one condition which is a constant acceleration in this case its a gravitational acceleration which is -9.8
![h = \frac{1}{2} g {t}^{2}](https://tex.z-dn.net/?f=h%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20g%20%7Bt%7D%5E%7B2%7D%20)
![t = \sqrt{ \frac{2 \times 60}{9.8 } } = 3.5s](https://tex.z-dn.net/?f=t%20%3D%20%20%20%5Csqrt%7B%20%5Cfrac%7B2%20%5Ctimes%2060%7D%7B9.8%20%7D%20%7D%20%20%20%3D%203.5s)
now we know that the initial velocity its zero :
so applu the another kinematic equation which is
![v = u - gt](https://tex.z-dn.net/?f=v%20%3D%20u%20-%20gt)
v is final velocity and u is the initial velocity and its equal zero.
v = - 9.8 × 3.5 = - 34.3
hello! it is velocity.
i say this because, Inertia is the tendency of an object to resist changes in its state of motion. ... The state of motion of an object is defined by its velocity - the speed with a direction.
Answer:
high frequent sound
Explanation:
because if its low than its slower.
