Answer:
A 3.0 kg mass moving at 9.0 m/s has more momentum than taht of a 5.0 kg mass moving at 5.0 m/s
Explanation:
given two masses m1 and m2 and their corresponding velocities v1 and v2
m1 = 3 kg
m2 = 5 kg
v1 = 9 m/s
v2 = 5 m/s
To calculate momentum of the masses:
We know that the momentum is given by the equation:
p = mv, where m is mass and v is velocity
momentum of mass m1 , p1 = m1 x v1
= 3 x 9 = 27 kg.m/s
momentum of mass m2, p2 = m2 x v2
= 5 x 5 = 25 kg.m/s
Hence p1>p2
Comparing above momentum value, it is inferred that the momentum of mass 3.0 kg is more that the momentum of mass 5.0 kg.
Answer:
I only know one
Explanation:
The strength of the gravitational field.
Answer:
3690 Newton
Explanation:
By using the F=ma formula we can find the Force if we know the mass and acceleration, so:
F= 180kg*20.5m/s^2
F=3690 kg*m/s^2 or 3690N

Answer:
The velocity from the personne flying over the island is
Explanation:
The island experiences a contraction of length, because the person who measures it, sees as if the island moves with a speed v. Relativistic Law, for an object with a velocity v and a length at rest Lo, and a length L at a velocity v :
