Answer:
32.46m/s
Explanation:
Hello,
To solve this exercise we must be clear that the ball moves with constant acceleration with the value of gravity = 9.81m / S ^ 2
A body that moves with constant acceleration means that it moves in "a uniformly accelerated motion", which means that if the velocity is plotted with respect to time we will find a line and its slope will be the value of the acceleration, it determines how much it changes the speed with respect to time.
When performing a mathematical demonstration, it is found that the equations that define this movement are the follow
Where
Vf = final speed
Vo = Initial speed =7.3m/S
A = g=acceleration =9.81m/s^2
X = displacement =51m}
solving for Vf
the speed with the ball hits the ground is 32.46m/s
Answer:
Rms speed of the particle will be
Explanation:
We have given mass of the air particle
Gas constant R = 8.314 J/mol-K
Temperature is given T =
We have to find the root mean square speed of the particle
Which is given by
So rms speed of the particle will be
The forces cancel out each other because they are equal and opposite. Therefore the net force is 0 and there will be no acceleration
