Answer:
t=v/a
Explanation:
Acceleration is defined as the rate of change of velocity with time. It is mathematically expressed as;
Acceleration = 
The change in velocity per unit of time is the acceleration
From this equation;
time = 
This expression is analogous to the expression chosen.
Explanation:
electricity is the flow of electrical power or charge
Answer:
T=1263.16N
Explanation:
A 958-N rocket is coming in for a vertical landing. It starts with a downward speed of 25 m/s and must reduce its speed to 0m/s in 8.0 seconds for the final landing. During this landing maneuver, what must be the thrust due to the rockets engines?
force is that which tends to cane a body state of rest or uniform motion in a straight line
it is also the pull or pus on an object.
the forces involved here to get the thrust on an object, are the weight and the force of gravity
W=mg
958=m*9.81
m=958/9.81
m=97.655kg
T=m(g+a)................................1
to get a
v=u+at
a=dv/dt
a=25/8
a=3.125m/s^2
acceleration is change in velocity per time
juxtaposing into the equation 1
T=97.655(9.81+3.125)
T=1263.16N
Answer:
1. 5 V
2. A₂ = 1.2 A
Explanation:
1. Determination of the voltage measured at R₃.
Voltage at R₁ (V₁) = 1 V
Voltage at R₂ (V₂) = 6 V
Total voltage (Vₜ) = 12 V
Voltage at R₃ (V₃) =.?
Vₜ = V₁ + V₂ + V₃
12 = 1 + 6 + V₃
12 = 7 + V₃
Collect like terms
12 – 7 = V₃
V₃ = 5 V
Thus, the voltage measured at R₃ is 5 V
2. Determination of A₂.
From the circuit diagram, we can see that the resistors are in series arrangement. This means that the same current will pass through each resistor.
Thus,
A₂ = A₁ = 1.2 A
