Answer to Question #70116 in Mechanics | Relativity for soso
object thrown the vorcity is 0 &the t=2 &the g=-9..8 what's the fainal vorcity ?
Assuming no air resistance we can use the projectile motion formulas. v_0=0 m/s. t=2 s. g=-9.8 m/s^2 . The final velocity is v=v_0+gt=0-9.8(2)= -19.6 m/s. The sign means that the positive direction is upwards. Answer: -19.6 m/s.
