Answer:
The condition necessary for the person to be able to remain stationary in mid-air is that there must be an upward force also referred to as THRUST
Explanation:
Thrust in Physics is defined as the force that propels, forces or pushes the mass of a certain object in a specified or particular direction.
Thrust can defined in the terms of a Jet pack can be defined as the force that is required to propel the mass of a person in an upward direction.
Based on the diagram that we have been shown the question, we can see that water is the fuel used to proper the user or person upwards hence, the jet pack used in the question is an HydroJet pack
The condition necessary for the person to be able to remain stationary in mid-air is that the propelling force called the thrust must be upwards such that it can overcome these 4 things:
a) Gravitational force
b) Mass of the jet pack user
c) Mass of the jet pack itself
d) The water which serves as fuel for the jet pack.
I think this is vectors. Sketch the two vectors A and B on the x axis and then find their magnitudes using cosine... i would like to know if i am correct.
Answer:
0.041 m
Explanation:
T = 2π√(L/g)
1 s = 2π√(L / (1.6 N/kg))
L = 0.041 m
The answer is b.) the momentum before the collision is greater than the momentum after the collision
Answer:
It gives our light which we need for probably everything.
