Answer:
To identify the momentum of object 1, you must multiply mass (m) and velocity(v) to find momentum.
Object 1 has momentum of 8 kg. m/s before collision.
Object 1 has momentum of 0 kg. m/s before collision.
The combined mass after the collision had a total momentum of 8 kg. m/s.
Explanation:
Momentum of the object is given by,
Momentum = mass × velocity
For object 1:
Momentum = mass × velocity
Momentum = 2 × 4
Momentum = 8 kg. m/s
For object 2:
Momentum = mass × velocity
Momentum = 6 × 0
Momentum = 0 kg. m/s
For object 1 + object 2:
Momentum = mass × velocity
Momentum = 8 × 1
Momentum = 8 kg. m/s
To identify the momentum of object 1, you must multiply mass (m) and velocity(v) to find momentum.
Object 1 has momentum of 8 kg. m/s before collision.
Object 1 has momentum of 0 kg. m/s before collision.
The combined mass after the collision had a total momentum of 8 kg. m/s.
1) F=q[vB], where q -> charge, v-> velocity, B-> magnetic field. [ , ] -> cross product.
2) f=q*v*B*sin(11°) {1}
3) 1.6f=q*v*B*sin(alpha) {2}
4) {2} / {1} -> 1.6=sin(alpha)/sin(11°) or sin(alpha)=1.6*sin(11°) --> alpha=arcsin (1.6*sin(11°))
So, alpha=17.7°=18°
If net external force acting on the system is zero, momentum is conserved. That means, initial and final momentum are same → total momentum of the system is zero.
Answer:
M = 5.882 10²³ kg
Explanation:
Let's use Newton's second law to analyze the satellite orbit around Mars.
F = m a
force is universal attraction and acceleration is centripetal
a = v²/ R
the modulus of velocity in a circular orbit is constant
v= d/T
the distance of the cicule is
d =2pi R
a = 2pi R/T
we substitute
- G m M / R² = m ( 
)
G M = 
M = 
the distance R is the distance from the center of the planet Mars to the center of the satellite Deimos
R = 23460 km = 2.3460 10⁷ m
the period of the orbit is
T = 1,263 days = 1,263 day (24 h / 1 day) (3600s / h)
T = 1.0912 10⁵ s
let's calculate
M = 
M = 509.73418 10²¹ /8.66640 10⁻¹
M = 58.817 10²² kg
M = 5.882 10²³ kg
