Answer:

La cantidad de movimiento es 1,92 kg*m/s.

Explanation:

La cantidad de moviemiento de la masa esta dado por:

p = mv

En donde:

p: es la cantidad de moviemiento o momento =?

m: es la masa = 4570 g

v: es la velocidad = 1,5 km/h

Tenemos que 1 kg = 1000 g, por lo tanto la masa es:

m = \frac{1 kg}{1000 g}*4570 g = 4,57 kg  

Ahora debemos convertir la velocidad de km/h a m/s:

v = 1,5 \frac{km}{h}*\frac{1000 m}{1 km}*\frac{1 h}{3600 s} = 0,42 m/s

Entonces, el momento es:

p = mv = 4,57 kg*0,42 m/s = 1,92 kg*m/s

Por lo tanto, la cantidad de movimiento es 1,92 kg*m/s.

Espero que te sea de utilidad!

loris [4]

Questions Diagram is attached below

Answer:

T=2.08s

Explanation:

From the question we are told that:

Speed of Train V=3.0m.s

Angle \theta=12\textdegree

Height of window h_w=0.90m

Width of window w_w=2.0m

The Horizontal distance between B and A from Trigonometric Laws is mathematically given by

 b=\frac{0.9}{tan12}

 b=4.23

Therefore

Distance from A-A

 d_a=2.0+4.23

 d_a=6.23

Therefore

Time Required to travel trough d is mathematically given as

 T=\frac{d_a}{v}

 T=\frac{6.23}{3}

 T=2.08s
