Sure why not I'll sub your channel
Its a cause Superman superpowers are the sun so it’s every energy of powers
It’s 16.25 meters per second you just add
Average speed = (total distance covered) / (time to cover the distance)
You only need the first and last points from the table.
First point: Position=0, Time=0
Last point: Position= 16.34, Time = 2.34 hours
Total distance covered = 16.34 (miles ? km ?)
Time to cover the distance = 2.34 hours
Average speed = (16.34 miles) / (2.34 hours)
<em>Average speed = 6.983 mile/hour </em>
Answer:
<em>12.23m/s</em>
Explanation:
<em>Let's recall that</em>
<em />
<em>The Initial momentum in (East)axis = 900 x 15 which is = 13500 N-s
</em>
<em>
</em>
<em>Initial momentum in (North) axis = 750 x 20 which is = 15000 N-s
</em>
<em />
<em>Total initial momentum becomes = √[(13500)^2 + (15000)^2] = 20180.44 N-s
</em>
<em> The initial momentum direction is at θ* East of North
</em>
<em />
<em>
Therefore, tanθ = 13500/15000 = 0.9 = tan42*
</em>
<em> tanθ=42</em>
<em>
</em>
<em>The speed of the wreckage after collection is,</em>
<em />
<em>Recall that The law of momentum conservation states that
</em>
<em>Momentum initial = Momentum final
</em>
<em>
</em>
<em>20180.44 = (900+750) x v
</em>
<em>
</em>
<em>v = 12.23 m/s</em>
