It will land at 14139.19 m away.

Explanation:

The expression for range d on level ground is given by;

d=v² sin (2Ф) /g where Ф is the fire angle and g is acceleration due to gravity

Given v=400m/s ,Ф= 60° and g=9.8 so,

d= 400² sin(120°) /9.8

d=(400²×0.86602540378) / 9.8

d=14139.19 m

How many times is a ray of light reflected by 2 plane mirrors placed parallel and facing each other
alexdok [17]

Answer:

the ray is reflected infinite number of times by 2 plane mirrors placed parallel to each other as each reflected ray would be the incident ray for the other.

Explanation:

the ray is reflected infinite number of times by 2 plane mirrors placed parallel to each other as each reflected ray would be the incident ray for the other.

Placing one mirror at an angle causes reflections to curve.

Un automóvil viaja a la velocidad de 10 m/s. Se acelera Durante 12s y aumenta su velocidad hasta 70 m/s ¿Que aceleración experim
VladimirAG [237]

Answer:

Aceleracion = 5 m/s²

Explanation:

Dados los siguientes datos;

Velocidad inicial = 10 m/s

Velocidad final = 70 m/s

Tiempo, t = 12 segundos

Para encontrar la aceleración;

Aceleración se puede definir como la tasa de cambio de la velocidad de un objeto con respecto al tiempo.

Esto simplemente significa que la aceleración viene dada por la resta de la velocidad inicial de la velocidad final a lo largo del tiempo.

Por lo tanto, si restamos la velocidad inicial de la velocidad final y la dividimos por el tiempo, podemos calcular la aceleración de un objeto. Matemáticamente, la aceleración viene dada por la fórmula;

Aceleracion = \frac{final \; velocidad  -  inicial \; velocidad}{tiempo}

Sustituyendo en la fórmula, tenemos;

Aceleracion = \frac{70 - 10}{12}

Aceleracion = \frac{60}{12}

Aceleracion = 5 m/s²

A high-speed railway car goes around a flat, horizontal circle of radius 480 m at a constant speed. The magnitudes of the horizo
kvv77 [185]

Answer:

Net force ( F ) = 208 N.

Speed of car ( v ) = 68.58 m/s.

Explanation:-

The radius ( r ) = 480 m.

Mass of passenger ( m ) = 65 kg.

Horizontal force ( f_{x} ) = 208 N.

Vertical force ( f_{n} ) = 637 N.

Net vertical component of force ( f_{x} ) = m*g - 637   = 65 * 9.8 - 637 =  0 N.

a ) magnitude of net force .

F = \sqrt{f^{2} _{x} + f^{2} _{y}  }   = \sqrt{208^{2} + 0^{2} }   = 208 N.

b) The speed of car.

f_{n}  = \frac{m*v^{2} }{r}    where v is the velocity.

637 = \frac{65 *v^{2} }{480}

v² = 4704

v = 68.58 m/s.
