Explanation:
energy conservation and fatigue management -tiredness is a common symptom of a heart attack and although rest is important activity is also required to facilitate a return to health. an occupational therapist said energy conservation and fatigue management is techniques to be implemented throughout the day. to help clients achieve their goals
The definition of P.E which stands for physical education is instruction that ranges in many areas to improve performance and management in athletic games. The definition of sports is an activity that requires skill and physical exertion of a team or an individual competing against others for fun or entertainment. I believe these are similar because without physical education kids cannot excel in their sports. P.E will help prepare them for this.However they are different because sports are solely focused on one topic and try to perfect that, physical education gives you many different things to work on.
Answer:
Explanation:
given ;
- coefficient of kinetic friction = 0.80
- considering the force acting in horizontal direction and from newton's 2nd law of motion;
- for vertical motion = Fn - mg = 0
- for horizontal motion = F = ma + miu mg = m( a + miu.g)
- therefore, F = miu mg where g = 9.81m/s^2
- plugging the values into the equation;
Horizontal force = 204.05N
Pregunta completa:
Un barco va a una velocidad de 45 ml/h, luego el capitán ordena acelerar hasta que la velocidad hasta que la velocidad sea de 60 mll/h. si la operación dura 30 minutos.
A cual fue la aceleracion?
B qué distancia recorre?
Responder:
30 millas / hora
26.25 mi
Explicación:
Dado que :
Velocidad inicial, u = 45 mi / hr
Velocidad final, v = 60 mi / hr
Tiempo, t = 30 minutos = 30/60 = 0,5 h
Aceleración, a = cambio de velocidad con el tiempo;
a = (v - u) / t
a = (60 - 45) / 0,5
a = 15 / 0,5
a = 30 millas / h²
Recorrido de distancia, S
S = ut + 0.5at²
S = 45 (0,5) + 0,5 (30) (0,5²)
S = 22,5 + 3,75
S = 26,25 millas
