30 grams because of conservation
Answer:
Los datos que tienes son:
m = 13 kg
d = 46 m
∪ = 0,45
g = 9,8 m/s²
Fr = ?
w = ?
Lo primero que haremos que calcular Fr
Fr = ∪mg
Fr = (0,45) (13 kg) (9,8 m/s²)
Fr = 57,33 N
Calculamos el trabajo realizado.
w = Fd
w = (57,33 N) (46 m)
w = 2637,18 Joules
Respuesta.
El trabajo realizado es 2637,18 Joules
Explanation:
For this case the centripetal force is given by:
Where,
m: mass of the object
v: tangential speed
r: rope radius
Substituting values in the equation we have:
Then, doing the corresponding calculations:
Answer:
The centripetal force exerted on the rope is:
Answer:
T = 6.43 x 10^3 N
Explanation:
As we know, T = w where w = 6.43 * 10^3 N So,
T = 6.43 * 10^3 N
(If the velocity is constant tension in the string is always equals to the hanging weight where weight can be calculated by mass and gravity as w = mg)
