Answer:
0.48 kgm/s
Explanation:
= mass of the particle = 2.43 μg = 2.43 x 10⁻⁶ x 10⁻³ kg = 2.43 x 10⁻⁹ kg
= velocity of the particle = 1.97 x 10⁸ m/s
= momentum of the particle
momentum of the particle is given as
inserting the values
kgm/s

Answer: approximately 4 seconds
Explanation:
1.52 is approximately pi/4
2pi rad is 360°
Pi/4 rad is 90°
So the chicken runs one-fourth of the path in one second so it runs the hole path in four minutes
Work is equal to a force over a distance and is equal to the change in kinetic energy, so

- Fd=ΔKE

<span>−Fd=1/2m<span>v22</span>−1/2m<span>v21</span></span>
<span>d=(1/2m<span>v22</span>−1/2m<span>v21</span>)/−F
</span>
We know that Ffric=kFnatural and Fnatural=mg so:
<span>d=(1/2m<span>v22</span>−1/2m<span>v21</span>)/−(k∗mg)</span><span>d=(−1/2<span>v21</span>)/−(k∗g)
</span><span>d=(−1/2×(14.6m/s<span>)2</span>)/−(0.137×9.8m/s)
</span><span>
d = 78.9m</span>
