Question #70116

object thrown the vorcity is 0 &the t=2 &the g=-9..8 what's the fainal vorcity ?

Expert's answer

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.

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.
