Which statement about the frog's motion is correct?

1.Ā On the way up its acceleration is 9.8m/s2 upward, and on the way down its acceleration is 9.8m/s2downward.

2.Ā On the way up and on the way down its acceleration is 9.8m/s2 downward, and at the highest point, its acceleration is zero.

3.Ā On the way up, on the way down, and at the highest point, its acceleration is 9.8m/s2 downward.

4.Ā At the highest point, it reverses the direction of its acceleration.

Water leaves a fireman's hose (held near the ground) with an initial velocity at an angle above the horizontal. Assume the water acts as a projectile that moves without air resistance. Use a Cartesian coordinate system with the origin at the hose nozzle position.

a) Using and , write an expression for the time the water travels to reach its maximum vertical height.

b) At what horizontal distance from the building base, where should the fireman place the hose for the water to reach its maximum height as it strikes the building? Express this distance, , in terms of Ā andĀ . Ā Ā Ā
