Karl Benz built his first automobile in 1885 in Mannheim.
Answer: 12.4 feet
Explanation:
If there is a smooth transition and there is no change in slopes, energy considerations can be used
The cube has a kinetic energy of
ke = mv^2/2 = 10 lbm * 20^2ft^2/s^2 / 2 = 2000 lbm-ft^2 / s^2
At the highest point when there is a gain in potential energy
pe = mgh = 10 lbm * 32.2 ft/s^2 * h ft = 322 lbm ft^2/s^2
If there is no loss in energies,
pe = ke
322h lbm ft^2/s^2 = 2000 lbm ft^2/s^2
h = 2000 /322 = 6.211 (ft)
= h / sin(30) = 12.4 ft
Answer:
The increase in pressure of the gas is found to be 15.92 KPa
Explanation:
The additional pressure is equivalent to the pressure exerted by the weight of the mass increased over the area of piston:
Increase in Pressure = ΔP = Weight/Area
ΔP = mg/πr²
m = mass = 25 kg
g = 9.8 m/s²
r = radius of cylinder = 7 cm = 0.07 m
ΔP = (25 kg)(9.8 m/s²)/π(0.07 m)²
ΔP = 245 N/0.01539 m²
<u>ΔP = 15.92 KPa</u>
Therefore, the increase in pressure of gas is 15.92 KPa.
