Most clouds form in the atmosphere when moist air rises expands and cool to the dew point. When the air above reaches its saturation point, the water vapor is attracted to dust particles which when they accumulate the hold on tho each other and form clouds. Evaporation and condensation is what causes saturation above. When the clouds become heavy enough with moisture, the water then fall to earth as rain. <span />
Answer:
a) v=3.166 m/s
b) μ=0.0169
Explanation:
a)
The motion is totally inelastic collision so the mass of the person and the mass of the sled in the second part of the motion are add both.
b)
The motion have friction so the force and coefficient can be find using Newtons second law where
Answer:After 2 seconds the object reach its maximum height of 80 feet.
Step-by-step explanation:
Consider the provided function.
The function is a downward parabola.
The object will reach its max height at the vertex of the parabola.
The vertex of the parabola is given by ,
Where the standard form is .
By comparing the provided function with the standard form.
a=-16, b=64 and c=16
Thus, the vertex are:
Now substitute the value of t in the provided function.
Hence, after 2 seconds the object reach its maximum height of 80 feet.
