When a driver applies brakes to keep a car going downhill at constant speed and constant kinetic energy the potential energy of the car decreases where does the energy go?

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.

How fast is Mach 1.3?

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).

Would a corkscrew on a roller coaster be potential energy or kinetic?

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).

How do you convert 760 mph to fps?

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

Is surface tension scalar or vector?

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

What is 120 miles per hour in kilometers per hour?

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

How do you calculate drag coefficient when you are not given drag force?

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.

How many kilometers is 176 miles an hour?

176 miles is equivalent to approximately 283 kilometers.

What is the greates velocity a falling object can reach called?

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.

How fast is 160kph in mph?

160kph = 100 mph

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

How much is 100 fpm in mph?

100 mph equates to 1,760 inches per second.

Which will have the greater rolling down an incline- a hoop or a solid disk?

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.

What is top speed of shogun pro 125?

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.

Which has more kinetic energy a 0.0020-kg bullet traveling at 400 ms or a 6.4 X 10 7 -kg ocean liner traveling at 10 ms 20 knots?

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!

What is the known variable for net force?

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

What is 200 kmh in mph?

Answer: 200 kmph is 124 mph.

124 mph - the conversion is 1kph = 0.62 mph

So - 200 kph * 0.62 = 124 mph

If you wanted to find out kph in mph, you would do the inverse.

So 120 mph / 0.62 = 200 km /h

When your car is traveling at 55 mph how fast is your body traveling?

When your car is traveling at a constant speed of 55 mph, your body inside the car is also moving at 55 mph relative to the car. This is because you are moving along with the car, experiencing the same speed as the vehicle you are in.

What is the difference between hypokalemic and hyperkalemic periodic paralysis?

Hypokalemic periodic paralysis is characterized by low levels of potassium in the blood during attacks, leading to muscle weakness or paralysis. In contrast, hyperkalemic periodic paralysis is characterized by high levels of potassium during episodes, resulting in muscle stiffness or weakness. Both conditions are genetic and involve dysfunction in ion channels that regulate potassium levels in muscle cells.

What characterizes kinetic apraxia?

Kinetic apraxia is a neurological condition that affects the ability to perform purposeful and coordinated movements, particularly with tools or objects. Individuals with kinetic apraxia may have difficulty with tasks such as using utensils, writing, or manipulating objects. This condition is often associated with damage to the parietal lobe of the brain.

How fast is 13 miles in 7 minutes?

To find out how fast 13 miles in 7 minutes, you would first convert 7 minutes to hours (7/60 = 0.1167 hours). Then you divide the distance (13 miles) by the time taken (0.1167 hours) to get the speed, which is approximately 111.5 miles per hour.

A ball is rolling along a straight and level path The ball is traveling at a constant speed of 2.0 ms The mass of the ball is 3.0 kg What is the kinetic energy of the ball?

The kinetic energy of the ball can be calculated using the formula: KE = 0.5 * mass * velocity^2. Plugging in the values, KE = 0.5 * 3.0 kg * (2.0 ms^-1)^2 = 0.5 * 3.0 kg * 4.0 m^2 s^-2 = 6.0 Joules. Therefore, the kinetic energy of the ball is 6.0 Joules.

22 knots equals MPH?

Notes: 1 knot = 1.15 mph 165 knots = 189.75 mph Answer: 188.60 164 x 1.15 = ?

How fast in kph is 369 mph?

369 mph is equivalent to approximately 594 kilometers per hour (kph).
