Answer:
The package strikes 207 m at the ground relative to the point.
Explanation:
Given that,
Speed = 46 m/s
Height = 101 m
Acceleration = 9.8 m/s²
We need to calculate the time
Using equation of motion
Put the value in the equation
We need to calculate the distance where the package strikes
Using formula of distance
Put the value into the formula
Hence, The package strikes 207 m at the ground relative to the point.
Answer:
Tying a 4 weight pound on a string is a potential energy because it is at rest but cutting it and letting it fall experiences a kinetic energy because it will be in motion.
Answer:
The speed of molecules in an "ideal" gas is related to the temperature
Advanced work indicates that
1/2 m v^2 = 3/2 k T where v^2 here is the mean square speed
This is true for H2, He, O2, Hg etc. and m is the molecular mass and k the Boltzmann constant
4.85 x10^4. This is the right answer says yahoo. I hope it helps.
momentum= mass × velocity
p= 50×18
momentum= 900 kg m/s
