What is the momentum of a 100 kilogram football player moving with a speed of 3.5 meters/second. The units should be written as kg m/s.

momentum=mass*velocity. Notice velocity is supposed to be a vector, therefore momentum is a vector. Apparently, the question writer is ignoring that.

To find the momentum of an object, you need to multiply its mass by its velocity. The equation for momentum is:

momentum = mass × velocity

In this case, the mass of the football player is given as 100 kilograms and the velocity is given as 3.5 meters/second. So, you simply need to multiply these two values together:

momentum = 100 kg × 3.5 m/s

To find the answer, calculate the product of these two values:

momentum = 350 kg⋅m/s

Therefore, the momentum of the 100 kilogram football player moving with a speed of 3.5 meters/second is 350 kg m/s.
