When you take a picture it pulls up people who asked the same question and they’ll have a answer you can use
P = √ [(px)^2 + (py)^2]
we know that px is 100 kg m/sec
and we know that py is 98 m/sec
So, to find out the momentum, you just need to insert the number into the equation
p = √(v1^2 + v2^2)
<span>p = </span>√<span>(98^2 + 100^2) </span>
<span>p = 140.01 </span>
<span>p = 1.4 x 10^2 k m/s</span>
More work was done in the skateboard that came to a stop because the one that rolled across the room moved on a surface with less friction while the second board used more work to move on a surface with much friction.
Answer:
4.8 watts
Explanation:
power = voltage * current = 12.0 * 0.40 = 4.8 watts
