There are four equations of uniform acceleration that you use for solving problems like this: * v = u + at * s = ((u+v)/2)t * s = ut + (at2)/2 * v2 = u2 + 2as Where:
u = initial velocity
v = final velocity
s = displacement
t = time
a = acceleration
You will also need to know Newton's second law of motion: * F= ma I can't help much more with your question without knowing which velocities you know, but I can tell you that the last one won't be much help.
Velocity = (velocity when time=0) + (Force x time)/(mass) ===> F = MA A = F/M V = V0 + A T
There is not enough information. Force = Mass*Acceleration. Acceleration is the rate of change in velocity. This requires information on change in velocity as well as the time over which the change took place. There is no information at all on the latter.

You cannot. Force = Mass*Acceleration or Mass*Rate of change of Velocity.
Without distance, you have to know time, initial velocity, and acceleration, in order to find final velocity.
Velocity = (velocity when time=0) + (Force x time)/(mass) ===> F = MA A = F/M V = V0 + A T
To calculate distance with velocity and weight, you can use the equation for work: Work = Force x Distance. The force can be calculated by multiplying the weight with gravity. Velocity can then be used to determine the time it takes for the object to travel that distance using the equation Distance = Velocity x Time.

The relationship between acceleration, initial velocity, final velocity, displacement, and time in a given motion is described by the suvat equations. These equations show how these variables are related and can be used to calculate one variable if the others are known. The equations are used in physics to analyze and predict the motion of objects.
velocity is a vector quantity. Its magnitude is given by (velocity)= (distance)/(time)
Force equals the mass times the rate of change of the velocity.
To find the force when given the mass and velocity of an object, you can use the formula: Force mass x acceleration. Acceleration can be calculated using the formula: acceleration change in velocity / time. By substituting the given values of mass and velocity into these formulas, you can determine the force acting on the object.

You cannot.
Velocity is in distance/time, so multiplied by 1/distance would give you 1/time. Hope this helps!
