Respuesta :

–9.8 m/s2

Just took it and got it right!

Answer : The correct option is (A) [tex]-9.8\ m/s^2[/tex]

Explanation :

The formula is given as :

[tex]v_y=a_yt[/tex]

Where,

[tex]v_y[/tex] is vertical component of velocity.

[tex]a_y[/tex] is the vertical component of acceleration.

In a projectile motion, the particle moves in a path under the influence of gravity.

So, the vertical component of acceleration is -g i.e acceleration due to gravity.

Hence, the correct option is (a) " [tex]a_y=-9.8\ m/s^2[/tex] ".
