1. A stone is thrown upwards with an initial velocity of 25 m/s at angle of 30° to the ground a. Show that the vertical component if the velocity at the starting is 12.5 m/s upwards.

Answer:

sin 30° = [tex]\frac{v_{y} }{25}[/tex]

Multiply each side by 25 to cancel the 25 under [tex]v_{y}[/tex]

(25)· sin 30° = [tex]v_{y}[/tex]

Multiply everything on the left side.

12.5 [tex]\frac{m}{s}[/tex] = vertical velocity component.

I attached a picture, I hope it helps.
