a ball is thrown upward. its initial verticle component of velocity is 10 m/s and its initial horizontal component of velocity is 2 m/s. what is the ball's speed 10 s later?

1 answer

the vertical component:
Vf=10-g*10=-88m/s
Vh=2

so add those vertical and horizontal components...

v=sqrt(2^2 + 88^2)
