A bullet is shot horizontally from a gun at 275ms How much does the bullet drop in flight if the targey is 50m away?

The bullet dropped .1612 meters.

To solve this type of problem, first determine how much time it took the bullet to travel to the target. Since Velocity = Distance / Time, Time = Distance / Velocity. In this problem Time = (50 m) / (275 m/s) = .1818 seconds.

Now use this time to figure out how far the bullet would have fallen due to gravity. You've probably seen this equation (or something like it) before:

Δy = vo*t - 1/2 * g * t2.

This equation means that to find how far the bullet fell you need to know how long it was falling, how fast it was falling at the very beginning, and what the acceleration due to gravity is. We already figured out how long the bullet was falling, we know that it wasn't falling at all at the very beginning, and gravity = 9.8 m/s2. This means that:

t = .1818

vo = 0

g = 9.8

So plug that in to the previous equation:

Δy = (0) * (.1818) - (1/2) * (9.8) * (.1818)2.

Δy = - .1612, with the - sign meaning the bullet went down and not up into the air.

What is low kinetic energy?

Low kinetic energy refers to an object or system having minimal motion or movement. Objects with low kinetic energy typically have slower speeds or are at rest. This is because kinetic energy is directly proportional to an object's mass and velocity – the lower these values, the lower the kinetic energy.

How many MPH are 110 kMPH?

110 kilometers per hour (kph) is equivalent to approximately 68.35 miles per hour (mph).

Does fireworks have kinetic energy?

Yes, fireworks have kinetic energy when they are being propelled into the air or when they are in motion. However, once they explode and release their energy in the form of heat, light, and sound, their kinetic energy is transformed into other forms of energy.

Is the average kinetic energy of particle in a block of ice at 0 degrees the same as or different from the average kinetic energy of the particle in a gas-filles container at 0 degrees Celsius?

The average kinetic energy of particles in a gas-filled container at 0 degrees Celsius is higher than in a block of ice at the same temperature. This is because the particles in a gas have more freedom of movement and therefore higher kinetic energy compared to the more restricted motion of particles in a solid like ice.

Is a baseball rolling on the ground kinetic or potential energy?

Assuming its not slipping, its kinetic, though its in two parts (to be added together):

1 . KE due to mass alone = 0.5 * mass * v2

2 . KE due to rotation = 0.5 * I * ((radians / second)2),

where I is the baseballs mass moment of inertia.

How fast is 90 kilometre a hour in miles an hour?

90 miles per hour is 144.84 kilometers per hour.

Which type of lever are you using when you chew your food?

Flex-ion and extension at temporo-mandibular joint. Here powerful Massetor and Temporalis muscles, one on either side is used. And medial to lateral or side to side movement (Grinding movement.) to grind the food. For which medial and lateral Pterigoid muscles are used.

What is faster 67.9 meters per second or 302 kilometers per hour?

302 kilometers per hour is faster than 67.9 meters per second. (67.9 meters per second equals 244.4 km per hour).

What causes a 02 zr 800 to run slugish past 50 mph?

A few common reasons for a sled running sluggishly past 50 mph could be a clogged fuel filter, dirty carburetors, or a problem with the exhaust system. It's also worth checking the spark plugs and making sure the air filter is clean to ensure optimal performance.

How does the mass and speed of an object affect the kinetic energy?

Kinetic Energy is 1/2 mass x the square of speed (KE = 1/2 mv^2)

How many mph dose 43cc gas scooter go?

A 43cc gas scooter typically travels at a speed of around 20-25 mph, depending on factors such as rider weight, road conditions, and terrain.

Is running 20 mph fast?

Yes, running at 20 mph would be considered fast for most people. The average running speed for adults is around 5-8 mph, so running at 20 mph would be significantly faster than average.

What is 40 km in mph?

40 kilometers per hour is equivalent to approximately 24.85 miles per hour.

How many miles jogged in an hour at the rate of 8.5 feet per second?

To convert feet per second to miles per hour, first convert feet to miles. There are 5280 feet in a mile. So, 8.5 feet per second = 8.5 * 3600 seconds in an hour / 5280 feet in a mile = 5.78 miles per hour.

What equation use for kinetic energy?

The equation for kinetic energy is KE = 0.5 * m * v^2, where KE represents the kinetic energy, m is the mass of the object, and v is its velocity. This equation shows that kinetic energy is directly proportional to the mass of the object and the square of its velocity.

What is is 45 mph in kmh?

45 miles is 72.4 kilometres. 45 miph is 72.4 kmh-1.

What is her kinetic energy if her mass is 70 kg and she is traveling at a rate of 6 meters per second?

The kinetic energy of an object is calculated using the formula KE = 0.5 * m * v^2, where m is the mass in kg and v is the velocity in meters per second. Plugging in the values given (m = 70 kg and v = 6 m/s), we find KE = 0.5 * 70 * 6^2 = 1260 J. So, her kinetic energy would be 1260 Joules.

How fast was a majungasaurus?

Majungasaurus was estimated to have been able to run at speeds of around 20-25 km/h (12-15 mph). It was a large theropod dinosaur, so it would have been fairly quick for its size.

How fast in mph is a 5.45 mile?

A 5 minute 45 second mile equates to a pace of 10.4347 mph

How fast is 3200kph in mph?

3200 kilometers per hour is approximately 1988 miles per hour.

What is the frequency of a 15 meter wave traveling at 250 meters per second?

The frequency of a wave is given by the formula: frequency = speed / wavelength. In this case, the wavelength is 15 meters and the speed is 250 meters per second. Therefore, the frequency of the 15 meter wave traveling at 250 meters per second would be 250 / 15 = 16.67 Hz.
