What is the velocity of an object that has the momentum of 4000 kg?

What is the velocity of an object that has the momentum of 4000 kg?

To calculate the velocity, we can use the formula: Velocity = Momentum / Mass Substituting the given values: Velocity = 4000 kg-m/s / 115 kg Simplifying this equation: Velocity ≈ 34.78 m/s Therefore, the velocity of the object is approximately 34.78 m/s.

What is the velocity of the 3 kg ball after the collision?

The velocity of the 3 kg ball is 4 m/s after the collision.

What is the formula for velocity with mass?

Mass is measured in (kg), and velocity is measured in meters per second (m/s). The SI unit for momentum is kg • m/s. You can rearrange the equation to calculate velocity if you know momentum and mass, Velocity = Momentum/Mass, or to calculate mass if you know momentum and velocity, Mass = Momentum/Velocity.

What is the formula for momentum velocity?

p = m v . You can see from the equation that momentum is directly proportional to the object’s mass (m) and velocity (v). Therefore, the greater an object’s mass or the greater its velocity, the greater its momentum.

What is the formula for the velocity of a ball?

The velocity of the falling ball as a function of time is v = -9.8 (m/s2) t j and its position as a function of time is r = (4.9 m – ½ 9.8 (m/s2) t2) j.

What is the formula for velocity after falling?

vf = g * t The value for g on Earth is 9.8 m/s/s. The above equation can be used to calculate the velocity of the object after any given amount of time when dropped from rest. Example calculations for the velocity of a free-falling object after six and eight seconds are shown below.

What is the velocity of a 3 kg particle?

The velocity of a 3.00kg particle is given by v = ( 8.00 t + 3.00 t 2 ) m / s ,with time tin seconds.At the instant the net force on the particle has a magnitude of 35.0 N, what are the direction (relative to the positive direction of the x axis) of (a) the net force and (b) the particle’s direction of travel?

What is the SI unit for velocity?

What is the SI unit of velocity? The SI unit of velocity is metres per second (m/s). Alternatively, the velocity magnitude can also be expressed in centimetres per second (cm/s).

Is velocity same as speed?

Why is it incorrect to use the terms speed and velocity interchangeably? The reason is simple. Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement. Put another way, speed is a scalar value, while velocity is a vector.

How do you find K in physics?

As a formula, it reworks Hooke’s Law and is expressed through the equation: k = – F/x. Where k is the spring constant, F is the force applied over x, and x is the displacement by the spring expressed in N/m.

What is the momentum of a 4 kg ball?

A 4 kg ball has a momentum of 12 kg m/s.

What is the momentum of a 1000 kg object that is not moving?

The momentum of any object that is at rest is 0.

How do you find final velocity with momentum?

If you know an object’s initial momentum and the force applied to it over a certain period of time, you can calculate its final momentum using the formula: Final Momentum = Initial Momentum + (Force x Time) Then, you can calculate the final velocity by dividing the final momentum by the object’s mass: Final Velocity = …

What is the momentum of 1000 kg car moving northward at 20 m?

p = mv = (1000kg)(20m/s) = 20000 kg m/s, northward • c.
