Answer:
![I=336.6kgm/s](https://tex.z-dn.net/?f=I%3D336.6kgm%2Fs)
Explanation:
The equation for the linear impulse is as follows:
![I=F\Delta t](https://tex.z-dn.net/?f=I%3DF%5CDelta%20t)
where
is impulse,
is the force, and
is the change in time.
The force, according to Newton's second law:
![F=ma](https://tex.z-dn.net/?f=F%3Dma)
and since ![a=\frac{v_{f}-v_{i}}{\Delta t}](https://tex.z-dn.net/?f=a%3D%5Cfrac%7Bv_%7Bf%7D-v_%7Bi%7D%7D%7B%5CDelta%20t%7D)
the force will be:
![F=m(\frac{v_{f}-v_{i}}{\Delta t})](https://tex.z-dn.net/?f=F%3Dm%28%5Cfrac%7Bv_%7Bf%7D-v_%7Bi%7D%7D%7B%5CDelta%20t%7D%29)
replacing in the equation for impulse:
![I=m(\frac{v_{f}-v_{i}}{\Delta t})(\Delta t)](https://tex.z-dn.net/?f=I%3Dm%28%5Cfrac%7Bv_%7Bf%7D-v_%7Bi%7D%7D%7B%5CDelta%20t%7D%29%28%5CDelta%20t%29)
we see that
is canceled, so
![I=m(v_{f}-v_{i})](https://tex.z-dn.net/?f=I%3Dm%28v_%7Bf%7D-v_%7Bi%7D%29)
And according to the problem
,
and the mass of the passenger is
. Thus:
![I=(66kg)(5.10m/s-0m/s)](https://tex.z-dn.net/?f=I%3D%2866kg%29%285.10m%2Fs-0m%2Fs%29)
![I=(66kg)(5.10m/s)](https://tex.z-dn.net/?f=I%3D%2866kg%29%285.10m%2Fs%29)
![I=336.6kgm/s](https://tex.z-dn.net/?f=I%3D336.6kgm%2Fs)
the magnitude of the linear impulse experienced the passenger is ![336.6kgm/s](https://tex.z-dn.net/?f=336.6kgm%2Fs)

Answer: Thus, the force is directed 72.5° above the horizontal.
Explanation:
The magnitude of the force, F = 15 N
let this force be detected at angle θ from the horizontal, then horizontal component of force is: F cos θ
and vertical component is F sin θ
Horizontal component is given,
F cos θ = 4.5 N
⇒15 N cos θ = 4.5 N
⇒ cos θ = 0.3
⇒ θ = cos⁻¹ 0.3 = 72.5°
Answer:
ans: 6 m/s
Explanation:
spaceship 1 has mass= 150kg
initial momentum of spaceship 1 = 900 kg•m/s
we know,
momentum = mass × velocity
so,
velocity = momentum/mass
= 900 / 150
= 6 m/s
since we know it was initial momentum so, velocity is initial speed,
