my grand daughter is having a awful time with this and i can't help her but if you would explain it to me maybe i can help here goes a skier with a mass of 48kg moves with a velocity of 11.45 m/s east. what is the skier's momentum p=mxv.

Once again, you have answered your own question. The answer is p = m v

(The x is just a multiplication symbol)

p = momentum
multiply mass (m) by velocity (v) to get the momentum.

The answer will have dimensions of kilogram meters per second.

Of course, I can help you with that! The momentum (p) of an object is calculated by multiplying its mass (m) and its velocity (v). In this case, the skier's mass is 48 kg and their velocity is 11.45 m/s to the east.

To find the skier's momentum, you simply multiply the mass and velocity:

p = m * v

p = 48 kg * 11.45 m/s

To get the answer, multiply 48 kg by 11.45 m/s. Using a calculator, you will find that the skier's momentum is 549.60 kg·m/s.

Please note that momentum is a vector quantity, which means it has both magnitude and direction. In this case, since the skier is moving east, the direction of the momentum is also east.
