A 1-kg discus is thrown with a vertical velocity of 19 m/s at an angle of 35 degrees from a height of 1.94 m. Do not factor in air resistance. Calculate the vertical and horizontal velocities.

Answer:

Vertical velocity   [tex]V_y = 10.89 \ m/s[/tex]

Horizontal velocity  [tex]V_x = 15.57 \ m/s[/tex]

Explanation:

If a 1 -kg is thrown vertically with a velocity of 19  m/s at an angle of 35 °C from a height 1.94 m

The vertical and horizontal component can be resolved as:

[tex]V_y = Vsin \theta \\ \\ \\\\V_x = Vcos \theta[/tex]

For Vertical component :

[tex]V_y = V sin \theta \\\\V_y = 19 * sin 35 \\ \\ V_y = 19* 0..5736 \\ \\ V_y = 10.89 \ m/s[/tex]

For horizontal velocity

[tex]V_x = V cos \theta \\\\V_x = 19 * cos 35 \\ \\ V_x = 19* 0.8192 \\ \\ V_x = 15.57 \ m/s[/tex]
