To represent in order how the animals
Answer:
x = 1.6 + 1.7 t^2 omitting signs
a) at t = 0 x = 1.6 m
b) V = d x / d t = 3.4 t
at t = 0 V = 0
c) A = d^2 x / d t^2 = 3.4 (at t = 0 A = 3.4 m/s^2)
d) x = 1.6 + 1.7 * (4.4)^2 = 34.5 (position at 4.4 sec = 34.5 m)
Let's supose that your object is the orange rectangle rotating around the blue circle (see picture attached)
r = 1.0 [m] is the radius of the circle (it's R in your problem).
ω [rad/s] - is the angular velocity of the object, it is measured in radians per second. We will compute it from the data you have
v [m/s] - is the tangential/linear speed, it is measured in meters per second
We know that the rotational speed is 10 revolutions per 4 seconds.
10/4 rev/s = 2.5 rev/s
We convert rev/s in rad/s and we get:
2.5 rev/s = 15.708 rad/s
So we found our angular speed: ω = 15.708 rad/s
The relationship between v and ω is:
v = ω · r = 15.708 · 1 = 15.708 m/s
Answer: the magnitude of the velocity around the circle is 15.708 m/s
Fusion is the energy source of stars. The energy that is being released from the gas collapse into a protostar causes the center of the protostar to become extremely hot. Once the core is hot enough, nuclear fusion commences. The fusion reaction is a very structured process, releasing a huge amount of energy.
Answer:
Los 0.0416km
esto se debe a que transponemos la fórmula acelerada y obtenemos Distancia = velocidad × tiempo
también recuerda transponer los segundos a horas viendo que la velocidad es por hora
También tenga en cuenta que no hablo español, así que esto fue extremadamente difícil
