Answer:

0.833 J

Explanation:

The initial kinetic energy of the spike is:

KE = ½ mv²

KE = ½ (0.52 kg) (3.7 m/s)²

KE = 3.56 J

23.4% of this energy is converted to internal energy.

U = 0.234 (3.56 J)

U = 0.833 J

If the tire reaches a temperature of 48 ∘c, what fraction of the original air must be removed if the original pressure of 250 kp

andrey2020 [161]

Assuming air as ideal gas and amount of air in no of moles is known then by gas law,

PV= nRT

Pressure is constant

P* (change in volume) = nR* (change in temperature)

A Mercedes-Benz 300SL (m = 1700 kg) is parked on a road that rises 15 degrees above the horizontal. What are the magnitudes of (

kogti [31]

Answer: See below

Explanation:

Given:

Mass of the Mercedes-Benz (m) = 1700 kg

Inclination of the road (θ) = 15.0

The free body diagram is shown in figure attached below

a) The normal force is equal to the cos component of the weight of the car.

$\begin{aligned}&f=m g \cos \theta \\&f=1700 \times 9.81 \times \cos 15 \\&f=16108.74 \mathrm{~N}\end{aligned}$

b) The static force will be equal to the weight's sin component.

$\begin{aligned}&f=m g \sin \theta \\&f=1700 \times 9.81 \times \sin 15 \\&f=4316.32 \mathrm{~N}\end{aligned}$
