How can you find the value of the impulse?

The value of an impulse is the change in momentum. If the mass remains constant it is the mass times the change in velocity.

How do you find velocity when given distance and mass?

The formula for finding that out is velocity = distance / mass

How do you find mass if you are given the momentum and the speed?

momentum = mass x velocity => mass = momentum / velocity

How do you find velocity when given the time and mass?

You can't. The mass is irrelevant to velocity. You need the distance.

How to find potential energy when only mass and velocity time is given?

To get the potential energy when only the mass and velocity time has been given, simply multiply mass and the velocity time given.

How can you find force when mass and velocity are given?

You cannot. Force = Mass*Acceleration or Mass*Rate of change of Velocity.

How do you find acceleration when given only mass and velocity?

You can't. Acceleration is change in velocity. If given a constant velocity, the acceleration is zero.

How do you find impulse?

The impulse of force is commonly used to calculate forces in collisions. Active formula. Impulse = Average force x time = mass x change in velocity

The impulse given to a ball with mass of 4 kg is 16 Nsec If the ball starts from rest what is its final velocity?

An impulse is simply a change of momentum, and momentum is defined as mass x velocity; so you just divide the momentum by the mass to get the velocity. Note about the units: newton x second is the same as kilogram x meter/second2.

What is mass of an object times its velocity?

Mass times velocity equals momentum. Mass times acceleration equals impulse. Half of mass times velocity squared equals kinetic energy.

How can impulse be increase?

Impulse is denoted as a change in momentum. Momentum has the units of kilogram meter per second. Which is mass times velocity. So you can decrease the time and increase the velocity to increase the impulse.

A ball with a mass M is falling on to the ground with some velocity V1 and raising with velocity V2 find the impulse?

Impulse = |change in momentum| Initial momentum = MV1 down Final momentum = MV2 up Missing momentum = impulse = M ( V1 - V2 )

How do you find height if velocity and mass are given?

1/2mv^2 = mgh

How do you calculate force when you are given time velocity and mass?

Time, velocity and mass do not provide enough information. If you are given a time interval, t, then you need the velocity at the start of the interval (= u) and at its end (v). Then F = m*(v - u)/t

Why will a lighter ball go faster than a heavy one?

Answer A large mass takes more energy to accelerate than a smaller mass.When a certain force it applied for a certain time, the impulse is given by the equation.I = mvI= impulse (energy)m= massv = velocity(speed)If the impulse is constant a smaller mass will result in more velocity and vice-versa.

How do you find mass if you given velocity?

That's not enough information. You need some additional information to calculate the mass.

How is impulse relative to momentum?

impulse (force x time) is equal to momentum (mass x velocity); Ft=mv

What is the relationship between impulse and change in momentum?

Impulse = Force x time Momentum = mass x velocity Ft = mv

How do you find velocity with mass and momentum?

momentum = mass X velocity

How do you find the kinetic energy of something if only the velocity is given?

You can't. You also have to know the mass, or have a way to find it.

How can i find velocity when given force and time?

If you have the mass, you can find the acceleration from Newton's Second Law, a=F/m where a is the acceleration, m is the mass, and F is the force. Then the velocity is given by the standard formula v=vo+at where v is the final velocity, vo the velocity at t=0, probably 0 in your case. If so v=at.

What impulse occurs when an average force of 10 N is exerted on a cart for 2.5 s?

You need a value for mass. velocity change = (time length of impulse * force) / mass

What is the unit of impulse in physics?

Same as the unit of momentum - an impulse is a transfer of momentum. Velocity x mass. Or the equivalent force x time.

How do you find the mass if you have the momentum?

Momentum alone cannot find the mass of an object as momentum is given by p = mv. To find mass m = p/v , velocity is also required.

Is the impulse momentum relationship related to newtons second law?

Yes, since f = m * a, and a = velocity change / time, you can shuffle this equation to : > velocity change = ((impulse) time * force) / mass
