Answer 2

Answer:

Explanation:

Vo=24m/s

theta=30o

t=2sec

a=g=-10m/s^2(g is negative bcz the projectile is going against gravity)

vertical component of velocity is equal to

Voy=Vosintheta

Vo=24sin30o

Vo=12m/s

using kinematic equation

Voy=Vi=12m/s

Vy=Vf=????

t=2sec

a=g=10m/s^2

Vf=Vi+at

Vy=Voy-gt

Vy=12-(2)(10)

Vy=-8m/s^2 (negative sign shows that the projectile is moving in negative y-direction)
