How high would a projectile go if it was launched from ground level with an initial speed of 26 m/s at an angle of 30 degrees ab
tigry1 [53]

Answer:

Vy = 26 m/s sin 30 = 13 m/s      vertical speed

t = Vy / a = 13 m/s / 9.80 m/s^2 = 1.33 sec     time to reach Vy = 0

H = Vy t + 1/2 g t^2

H = 13 m/s * 1.33 sec - 1.33^2 * 9.8 / 2 m = 8.62 m

A frog hops 5m east and 2m north. What is the magnitude of the frogs total displacement in m?
TiliK225 [7]

As per the question a frog jumps 5 m towards east.

Frog again jumps 2 m north.

Let the displacement along east is denoted by vector A and the displacement towards north is denoted as vector B.

Hence magnitude of A = 5 m

           Magnitude of B = 2 m

We are asked to calculate the total displacement.

Here the angle between them is 90 degree as A is towards east and B is towards north.

As per parallelogram law of vector addition,the magnitude of total displacement [R] will be-

                            R=\sqrt{ A^{2} +B^{2}+2AB\cos\theta}

                            =\sqrt{ 5^{2}+ 2^{2}+2*5*2 cos 90}

                            =\sqrt{25+4+0} m  [cos90= 0]

                            =\sqrt{29} m

                            = 5.38516 m   [ans]

¿Cuánto se demora el sonido en recorrer 3 metros de un cable de cobre, si su rapidez en él es de 3810 m/s
IgorLugansk [536]

Answer:

1270 segundos

Explanation:

Dada,

Velocidad ( v ) = 3810 m/s

Distancia ( s ) = 3 m

Encontrar : -

Tiempo que tarda el sonido en viajar ( t ) = ?

Fórmula : -

s = d / t

t = d / s

= 3810 / 3

t = 1270 segundos
