Question

question 7 (1 point) use the momentum equation (or the momentum triangle below) to calculate the mass of an object with a momentum of 6400 kg m/s and a velocity of. m = p / v

Explanation:

Step1: Recall momentum formula

The formula for momentum is $p = mv$, where $p$ is momentum, $m$ is mass and $v$ is velocity. We need to solve for $m$, so $m=\frac{p}{v}$.

Step2: Substitute given values

Given $p = 6400\ kg\cdot m/s$. But the velocity value is missing in the question. Assuming the velocity $v$ is known, if we had a value for $v$ (say $v = 8\ m/s$ for example), then $m=\frac{6400}{v}$. If $v = 8\ m/s$, then $m=\frac{6400}{8}=800\ kg$.

Since the velocity value is not provided in the actual question, we can't give a definite numerical answer. If we assume a velocity value of $v$ (in $m/s$), the mass formula is $m=\frac{6400}{v}$ (in $kg$).

Answer:

Since the velocity value is missing, we can't calculate a specific mass value. The general formula for mass in terms of the given momentum $p = 6400\ kg\cdot m/s$ and velocity $v$ is $m=\frac{6400}{v}$ (in $kg$).
