How do you find velocity given only the time?
You cannot. You must have distance (or displacement). If you know it is from a standing start then accelaration will do.
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.
What is the mass of a .5 in diameter glass marble?
I don't believe there is a way to find the mass of an object knowing only the diameter of the object. If you had the volume, or some other measurements sure. the best bet would be just to weigh it, or find the volume using the principles of displacement.
How do you find velocity given only mass and speed?
You can't, because you don't have enough information. In order to find velocity, you need to be able to find the speed and the direction of motion. You have the speed, but you have no information that you can use to determine the direction in which the object is moving. Mass doesn't help.
How do you find the mass of an irregular object?
you use the water displacement test. the mass of the displaced water is equal to the mass of the object. because the density of water is one, this means that the volume of the water is equal to the mass of the object * * * * * That is only true if the body floats. Two blocks of different metals, but of the same size will displace the same volume of water. Their masses will not be the same.
