The unknown mass can be determined by substituting the values of F, v, and r into the equation and solving for m.

You can calculate the unknown mass using the radius of the circular path and the tangential speed of the object.

This is done by using the equation F = ma, where F is the centripetal force needed to keep the object in its circular path, m is the mass of the object and a is its centripetal acceleration.

To calculate the centripetal acceleration, you can use the equation a = v² / r, where v is the tangential speed and r is the radius of the circular path.

To find the centripetal force needed to keep the object in its circular path, you can use the equation F = m(v² / r). Solving for m, you get m = F / (v² / r).

Therefore, the unknown mass can be determined by substituting the values of F, v, and r into the equation and solving for m.

The centripetal force required to keep the 23.0 kg child riding a playground merry-go-round that is rotating at 50.0 rev/min, and is 2.50 m away from its center is 623.0 N.

The centripetal force (Fc) required to keep the 23.0 kg child riding a playground merry-go-round that is rotating at 50.0 rev/min, and is 2.50 m away from its center is 623.0 N.

Formula to calculate the centripetal force:

Fc = mv^2/r

Where,

m = mass of the child = 23.0 kg

v = velocity of the child = 2πr/T = 2π * 2.5/60 = π/12 m/s

r = radius of the merry-go-round = 2.5 m

Substituting the values in the formula,

Fc = 23 * (π/12)^2 / 2.5

Fc = 623 N

The truck is moving at approximately 140 km/h if the outgoing radar has a frequency of 97 hz and the returning echo from the truck has a frequency of 18.1 hz higher.

The Doppler Shift Formula can be used to resolve this because it is

The amount of heat energy gained by the bullet due to friction as it comes to a stop can be calculated using the equation:

Q = μ * F * x

where Q is the heat energy, μ is the coefficient of friction, F is the frictional force, and x is the distance traveled. However, without more information on the coefficient of friction and the distance traveled, the exact amount of heat energy gained by the bullet cannot be determined.

The magnitude of the acceleration when the crate starts to slip will depend on the coefficient of friction between the crate and the floor.

Generally, the acceleration will be equal to the coefficient of friction multiplied by the acceleration due to gravity, which is 9.8 m/s2. So, if the coefficient of friction is 0.5, the acceleration of the crate will be 4.9 m/s2.

the magnitude of the car's acceleration is 2.5 m/s^2.

The change in velocity (delta v) over time can be used to determine the amount of an automobile's acceleration (delta t). Acceleration is calculated as follows:

a = Δv / Δt

Given that the car begins at rest (with a beginning velocity of v0 = 0 m/s) and reaches a final speed of 25 m/s after 10 seconds, the acceleration can be calculated as follows:

v = beginning velocity - ultimate velocity.

Δv = 25 m/s - 0 m/s

Δv = 25 m/s

Δt = 10 s

A = 25 m/s/10 s for a = v/t.

When it comes to sound, the law says that if a sound gets louder, people will only notice a difference if the change in volume is big enough.

To calculate the minimum increase in the volume required for a sound to be perceived as noticeably louder, we can use the formula for the Weber-Fechner law: V' = V * 10^(1/10) where,

Let's say that a car alarm is sounding off at 60 units of volume. To find the minimum increase in the volume required for the car alarm to be perceived as noticeably louder, we can plug in the initial volume into the formula:
