If v = 5.00 meters/second and makes an angle of 60° with the negative direction of the y–axis, calculate the possible values of vx.

Respuesta :

Vx = ± 5.00(sin 60°) = ±4.33 m/s ANS

Answer:

so two possible velocities are +4.33 m/s or -4.33 m/s

Explanation:

As we know that initial speed of the object is

[tex]v_i = 5.00 m/s[/tex]

here the angle made by the object velocity with y axis is given as

[tex]\theta = 60 degree[/tex]

now the x component of the velocity is given as

[tex]v_x = \pm v sin60[/tex]

[tex]v_x = \pm 5.00 sin60[/tex]

[tex]v_x = \pm 5.00 (0.866)[/tex]

[tex]v_x = \pm 4.33 m/s[/tex]

so two possible velocities are +4.33 m/s or -4.33 m/s
