Magnitude of momentum = (mass) x (speed)
Mass = 50 kg
Speed = (400/50) meters per second
Magnitude of momentum = (50) x (400/50) = 400 kg-m/sec
About 365.5 meters a minute.

he completes it in 69.9 seconds
Suppose a runner covers a distance of 5322 feet in a 6 minutes and 11,531 feet in 13 minutes. So how much distance does the runner cover in 16 minutes?
The answer depends on the distance for the race. A marathon runner could not maintain the speed attained by a sprint runner.
Momentum= 400.
The average speed of the runner is 1500m/(180 + 49.67) seconds = 6.531 m/s or 13 knots.
Since two runners finished in 80 seconds, the average of 80, 80, 72, and 68 must be found. This average is ? seconds. ANS IS 75No it is 73.333333 actually It's 75 even. Add all Four times Divide by four and you have you average.
Divide 315 by 9. 315 / 9 = 35 fps
About 365.5 meters a minute.
He is running at an average speed of 21.31 mph.
The duration of Storm Runner is 60.0 seconds.
315 feet in 9 seconds = about 35 feet per second.
1 and 5/6m per seconds
52 minutes 8.58 seconds.
Magnitude of average acceleration = (change of speed) divided by (time for the change)Average 'A' = (6 - 4) / 20 = 2/20 = 0.1 meter per second2-- That's the average over the 20 seconds. We don't know anything about thevalue of the acceleration at any particular instant during the 20 seconds.-- We're working entirely with scalars ... speed, not velocity, and magnitude ofacceleration ... since we don't know anything about the runner's direction atany time during the whole event.
The duration of Adventures of the Road Runner is 1560.0 seconds.
