You cannot.

Force = Mass*Acceleration or Mass*Rate of change of Velocity.

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

Force equals mass times acceleration.

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.

Velocity = (velocity when time=0) + (Force x time)/(mass) ===> F = MA A = F/M V = V0 + A T

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

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

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

Force = Mass * Acceleration (F = m * a)Therefore, if the mass of an object is increased, then the force required to accelerate to a given velocity will be greater. If the mass is decreased, then the force required to accelerate that object to a given velocity will become smaller.

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

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.

Not enough information. You can calculate force by Newton's Second Law, but in this case, there is no way to know how fast the velocity changes - or whether it changes at all.

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

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.
