What is the velocity of a 65 kg runner with 90 kg m/s of momentum.

Explanation:

Momentum is the product of mass and velocity.

We know the mass is 65 kilograms and the momentum is 90 kilograms meters per second.

Substitute the values into the formula.

Since we are solving for velocity, we must isolate the variable (v). It is being multiplied by 65 kg. The inverse of multiplication is division, so we divide.

The kilograms cancel when divided.

Let's round to the nearest hundredth. The 1 (in the thousandth place) tells us to leave the 6.

The velocity is approximately 1.46 meters per second.

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
