Responder:
A. Ff = 300 N N = 784,8 N
Explicación:
Dado
Masa del cuerpo = 80 kg
Fuerza de movimiento Fm = 300N
Dado que el cuerpo no está acelerando, la fuerza de fricción (Ff) es igual a la fuerza de movimiento que actúa sobre el cuerpo, ya que la fuerza de fricción es una fuerza de oposición, es decir, Fm = Ff
Dado que Fm = 300N, Ff = 300N
La reacción normal que actúa en el cuerpo es igual al peso.
N = W = mg
g es la aceleración debida a la gravedad
g = 9,8 m / s
N = mg
N = 80 (9,81)
N = 784,8N
Por tanto, la fuerza normal que actúa sobre el cuerpo es 784,8 N
Answer:
Part b)
Part c)
Explanation:
The two components of the velocity of the ball is given as
Part a)
now we know that the displacement in y direction is given as
so we have
Part b)
Distance of the ball in x direction of the motion is given as
Part c)
In x direction the velocity will remain the same always
while in Y direction we can use kinematics
Yes. True. Resistors slow the current down at the point in the circuit.
Hope it helps you...

Here are the methods that I think that kinesiologists might use to study physical activity. These are exercise and Skilled movement. According to Kinesiology, physical activity is any movement that is intentional, voluntary, and is directed to achieving a desired goal. Hope this answers your question.
Answer:
The motion will increase since there is more energy given since their is less to distribute to.
