vladimir1956 [14]

Answer:

$v_{avg}=35m/s$

Explanation:

To calculate the average velocity we must know the distance traveled and do $v_{avg}=\frac{d}{t}$ . The distance traveled is $d=\frac{at^2}{2}$ , so we need to calculate the acceleration, which, since it's uniform, is $a=\frac{\Delta v}{\Delta t}=\frac{v_f}{t}$ . Putting all together:

$v_{avg}=\frac{d}{t}=\frac{at^2}{2t}=\frac{at}{2}=\frac{v_ft}{2t}=\frac{v_f}{2}=35m/s$

How much pressure is created by a circular piston that is 0.24 meter in diameter

Vedmedyk [2.9K]

Answer:

4000 N/m²

Explanation:

Area = πr²

Area = π x 0.12² (diameter/2)

Area = 0.05 m²

Pressure = force/area

Pressure = 200/0.05

Pressure = 4000 N/m²

Hope this helps!
