Kinematics

Mach 9.6 is approximately 11,700 kilometers per hour or about 7,300 miles per hour. It is nearly 9.6 times the speed of sound in air at sea level.

30.66 meters per second is equivalent to approximately 68.56 miles per hour.

Gas particles are so small in relation to the distances between them that their individual volumes can be assumed to be insignificant. The large relative distances between the gas particles means that there is considerable empty space between the particles. This assumption that gas particles are far apart explains the important property of gas compressibility: A gas is easily compressed because of the space between the particles. Therefore, the energy of a collision is absorbed when the gas particles are forced closer together.

The second property of gas particles assumed by the kinetic theory is that no attractive or repulsive forces exist between the particles. As a result, gases are free to move inside their containers. In fact, a gas expands until it takes the shape and volume of its container.

The third assumption is that gas particles move rapidly in constant random motion. The particles travel in straight paths and move independently of each other. Only when a particle collides with another particle or object does it deviate from its straight line path. Kinetic theory assumes further that these collisions between gas particles are perfectly elastic, which means that during a collision the total amount of kinetic energy remains constant and that the kinetic energy is transferred without loss from one particle to another. You should also recall that the average kinetic energy of a collection of gas particles in directly proportional to the Kelvin temperature of the gas.

45 km/h is 27.9617 mph

Due to mach speeds being the percentage of the speed of sound and the speed of sound changing with air density and temperature the answer varies but mach .95 at 30,000ft is 645.05 mph

The speed of sound is approximately 767 mph at sea level. To break the sound barrier, an object would need to travel faster than this speed, so it would have to be moving faster than 767 mph.

velocity is a vector quantity and also acceleration is a vector quantity. Suppose my automobile is travelling in north direction and I apply brakes to it then until the automobile stops it will move in north direction while the acceleration will act in south direction as brakes are applied.

50 kilometers per hour is 31.07 miles per hour.

In a standard car, the energy becomes heat in the brakes. Keep that up for

too long, and they'll burn up. I have personally had the pleasure of coming

down a mountain in China where that technique was applied, and seeing both

front tires ignite simultaneously.

In an electric or hybrid car, some of the energy goes back in to recharge the batteries.

Mach 1.3 is 1.3 times the speed of sound, which is approximately 1,570 kilometers per hour (975 miles per hour) at sea level. So, Mach 1.3 would be around 2,041 kilometers per hour (1,269 miles per hour).

A corkscrew on a roller coaster would have kinetic energy as it moves through the track, turning potential energy (stored energy due to its height) into kinetic energy (energy of motion).

3,600/5,280 gives you 1 fps in m.p.h Example: 52.8 f.p.s = 36 m.p.h.

surface tension is a scalar quantity because it has no specific direction.

120 km/h = 331/3 m/s

≈ 33.33 ms-1

1 km = 1000 m

⇒ 120 km = 120 x 1000 m

= 120000 m

1 hr = 3600 sec

⇒ 120000 m/hr = 120000 ÷ 3600 m/s

= 331/3 m/s

≈ 33.33 m/s

You can calculate the drag coefficient by using the formula Cd = Fd / (0.5 * ρ * A * V^2), where Cd is the drag coefficient, Fd is the drag force, ρ is the air density, A is the reference area, and V is the velocity of the object. Given these values, you can rearrange the formula to solve for the drag coefficient.

176 miles is equivalent to approximately 283 kilometers.

The greatest velocity a falling object can reach is called terminal velocity. Terminal velocity occurs when the force of air resistance on the object matches the force of gravity pulling it down, resulting in a constant speed.

160kph = 100 mph

160 km is a DISTANCE, and can't be converted to a speed.

100 mph equates to 1,760 inches per second.

A solid disk will roll faster down an incline compared to a hoop because more mass is concentrated at the center of the disk, which increases its rotational inertia and supports the rolling motion. The distribution of mass in a hoop is more spread out, leading to lower rotational inertia and a slower rolling speed.

The top speed of a Shogun Pro 125 motorcycle typically ranges between 100-110 km/h, depending on factors such as rider weight, road conditions, and maintenance of the bike.

Let's see.

KE = 1/2mV^2

Bullet:

KE = 1/2(0.0020 kg)(400 m/s)^2

= 160 Joules

-------------------------------

Ocean Liner:

KE = 1/2(6.4 X 10^7 kg)(10 m/s)^2

= 3.2 X 10^9 Joules

-----------------------------

The linear by a long shot!

The known variable for net force is "F_net." It represents the sum of all forces acting on an object in a particular direction.
