Question

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.

Answer 1

Vx = ± 5.00(sin 60°) = ±4.33 m/s ANS

Answer 2

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

$v_i = 5.00 m/s$

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

$\theta = 60 degree$

now the x component of the velocity is given as

$v_x = \pm v sin60$

$v_x = \pm 5.00 sin60$

$v_x = \pm 5.00 (0.866)$

$v_x = \pm 4.33 m/s$

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