Thermal energy from the coffee is transferred to the mug.
Answer:
The ball impact velocity i.e(velocity right before landing) is 6.359 m/s
Explanation:
This problem is related to parabolic motion and can be solved by the following equations:
----------------------(1)
---------(2)
----------------------- (3)
Where:
x = m is the horizontal distance travelled by the golf ball
is the golf ball's initial velocity
is the angle (it was a horizontal shot)
t is the time
y is the final height of the ball
is the initial height of the ball
g is the acceleration due gravity
V is the final velocity of the ball
Step 1: finding t
Let use the equation(2)
![t=\sqrt{\frac{2 y_{o}}{g}}](https://tex.z-dn.net/?f=t%3D%5Csqrt%7B%5Cfrac%7B2%20y_%7Bo%7D%7D%7Bg%7D%7D)
![t=\sqrt{\frac{2 (12.5 m)}{9.8 m/s^{2}}}](https://tex.z-dn.net/?f=t%3D%5Csqrt%7B%5Cfrac%7B2%20%2812.5%20m%29%7D%7B9.8%20m%2Fs%5E%7B2%7D%7D%7D)
s
Substituting (6) in (1):
-------------------(4)
Step 2: Finding
:
From equation(4)
![67.1 =V_{o}(1) 1.597](https://tex.z-dn.net/?f=67.1%20%3DV_%7Bo%7D%281%29%201.597)
![V_0 = \frac{6.71}{1.597}](https://tex.z-dn.net/?f=V_0%20%3D%20%5Cfrac%7B6.71%7D%7B1.597%7D)
m/s (8)
Substituting
in (3):
v =42 .01 - 15.3566
V=26.359 m/s
The answer is weak.
The interaction of nature that will depend on the distance through the
way it acts and involved in beta decay is the weak interaction or the weak
force. This interaction is the responsible for radioactive decay which also
plays a significant role in nuclear fission.
