Question

physics problem.

Answer 1

A ball is thrown horizontally from the top of a 20-m high hill. It strikes the ground at an angle of 60◦ . With what speed was it thrown?

Answer 2

hmm. if it would strike at almost 90°, that would indicate it just fell down.

also, if it was shot by a gun it would still have lots of velocity that is greater than the gravity when it touches the ground.

Answer 3

hmmm ok. Any idea how to solve it?

Answer 4

theoretically, the push horizontally does not change the time it takes for the ball to fall down

Answer 5

Right. so it should take around 2 seconds right?

Answer 6

please post this in the physics section, thanks

Answer 7

Ok. sorry.
