Question

After a snowstorm a boy and girl decide to have a snowball fight. The girl uses a large slingshot to shoot snowballs at the boy. Assume that the girl fires each snowball at an angle 0 from the ground and that the snowball travel with an initial velocity of V0..

1.in terms of the inital velocity V0 and the lanch angle 0 for what amount of time (delta T) will a snowball tracel bfore it reaches its minimum height ab0ve the grpond

Answer 1

the height in meters is

h(t) = (Vo sinθ)t - 4.9t^2

Now just find t when h=0.

You sure overload the symbol 0.
