By conservation of momentum,
Pinitial = Pfinal
m1v1 + m2v2 = (m1 + m2)*vf
m1 = mass of skateboard = 1.13 kg
m2 = mass of cat = 0.93 kg
v1 = initial velocity of skateboard = 4.28 m/s
v2 = initial velocity of cat = 0 m/s
vf = final velocity of skateboard-cat combo
So plug in the values and solve for vf,
1.13(4.28) + 0.93(0) = (1.13 + 0.93)vf
vf = 2.35 m/s
Answer:
The work could be either positive or negative, depending on the direction the object moves
Explanation:
"Light year" is a distance, not a speed. It's the distance light travels in one year, at the speed of 299,792,458 meters per second.
Answer:
<u>Jupiter and Saturn</u>
Explanation:
Giant planets -
Giants planets have maximum moons ,
for example ,
Jupiter and Saturn .
Jupiter have 63 moons ( according to 2009 calculation ) , where , 8 moons are the regular satellites , 4 moons are spherical and large , 4 moons are small and close to Jupiter , in addition to it Jupiter have 55 irregular satellites .
Second highest moon is with planet Saturn , with 61 moons .
Many of moon's are thought to have been captured from the small-body population during the formation of the solar system .
