Answer:
The impact speed of the cup is 3.83 m/s.
Explanation:
Given that,
Height = 0.75 m
We need to calculate the impact speed of the cup
Using kinetic and potential energy
[tex]K.E=P.E[/tex]
[tex]\dfrac{1}{2}mv^2=mgh[/tex]
Where,
M = mass of the cup
v = velocity of cup
g = acceleration due to gravity
h = height
Put the value into the formula
[tex]\dfrac{1}{2}v^2=gh[/tex]
[tex]v=\sqrt{2gh}[/tex]
[tex]v=\sqrt{2\times9.8\times0.75}[/tex]
[tex]v=3.83\ m/s[/tex]
Hence, The impact speed of the cup is 3.83 m/s.
