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

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

Power is equal to Force times velocity; P=Fv. You are given the 'speed', which I assume to be velocity. You also have acceleration. In order to find F, you need first to find the mass, which you can calculate from the weight, Fg, by dividing by the acceleration due to gravity, 9.8. You then have the mass. From here, multiply mass times acceleration times the velocity.

Tangential velocity is equal to (mass x velocity^2)/radial distance

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

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

First note the following formulaes Velocity= Distance/Time.............................................1 Acceleration= Change in velocity/Time..........................2 Therefore say if V2 and V1 is given the difference between them is the change in velocity if not then consider the value of speed as change in velocity Now find the Time from second equation = V(speed)/A(accel)..............3 Make eq 1 as Distance =Velocity*Time Since you have the value of velocity and Time substitute and get the value of Distance travelled Please note that the referred problem is independent of mass

In Newtonian mechanics using momentum, p, mass, m, and velocity, v, p=m*v. You will need mass and velocity to find momentum, generally. To find velocity you can know time and distance, v=d/t.

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

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.

Catapult and not canapult. Any way for a given energy as mass of the object increases then distance would get decreased as velocity gets reduced.

Impluse = m x v

1/2mv^2 = mgh

To calculate the velocity we would have to know the mass of the first object because we need it to find the force of gravity between the two bodies to then find out the net distance and time.

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

That's not enough information. distance x force = work, but mass is unrelated.

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

the final velocity assuming that the mass is falling and that air resistance can be ignored but it is acceleration not mass that is important (can be gravity) final velocity is = ( (starting velocity)2 x 2 x acceleration x height )0.5

Assuming you start from rest (0) and accelerate uniformly. > acceleration = distance / (0.5 * time2), then having found acceleration: > final velocity = acceleration * time

Force equals the mass times the rate of change of the velocity.

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.

The distance doesn't depend on the mass.

You can't tell that from the information given.Plus ... the answer doesn't depend on the vehicle's mass. In principle, a battleship and a bicycletraveling at the same speed can come to a halt in the same distance. The difference is: how muchforce it takes to stop them in a given distance. (It takes more force to stop the battleship.)In the given question, if we knew the car's initial velocity, we could calculate the force requiredto stop it in 3 meters. And if we knew the force that stopped it in 3 meters, we could find theinitial velocity. But neither number is given, so all we can do as we read the question is say"that's nice", and go on to the next question.

momentum = mass X velocity

Mass by itself has no effect on velocity. In terminal velocity (velocity of an object falling through a fluid) the mass tovolume ratio (density) can change the final velocity at any given medium density, but in acceleration in a vacuum there is no impact from mass on velocity.
