Answer:
El alcance de la bala es 3464,1 m.
Explanation:
El alcance de la bala se puede calcular como sigue:
En donde:
y: es la altura final = 0
: es la altura inicial = 0
x: es el alcance
θ: es el angulo respecto a la horizontal = 30°
: es la velocidad inicial = 200 m/s
g: es la gravedad = 10 m/s²
Entonces, tenemos:
Por lo tanto, el alcance de la bala es 3464,1 m.
Espero que se te sea de utilidad!
Answer:
12
Explanation:
i agree the answer is 12 because the acceleration is given by the difference in the velocity divided by the time taken
a=v-u/t
60-0/5
=12m/s²
I hope this helps
Answer:
T= 19.74 N
Explanation:
The tension in the string will be equal to centripetal force on the ball. (Newton's 3rd law, equal acting and reacting forces acts on a body)
T = Fc
Fc = m w ²r
here:
m = 0.25 kg, r = 0.5 m
w = 2 rps = 2 * 2π rad/s ( ∴ 1 revolution = 2π radians )
w = 4π rad/s
Fc = m w ²r = 0.25 * ( 4π )² * 0.5 N
Fc = T = 19.74 N
T= 19.74 N
