A woman on a bridge 71.0 m high sees a raft floating at a constant speed on the river below. Trying to hit the raft, she drops a stone from rest when the raft has 7.40 m more to travel before passing under the bridge. The stone hits the water 5.40 m in front of the raft. Find the speed of the raft.
7. A ball is thrown vertically downward from the edge of a bridge 24.0 m high with an initial speed of 12.0 m/s. The ball falls all the way down and strikes the water below. Determine the time it takes the ball to strike the water. 3.75 8. A photographer in a helicopter ascending vertically at a constant rate of 1.2 m/s accidentally drops m above the ground. (a) How long will it take the camera to reach the ground?...
A woman on a bridge 98.3 m high sees a raft floating at a constant speed on the river below. She drops a stone from rest in an attempt to hit the raft. The stone is released when the raft has 7.66 m more to travel before passing under the bridge. The stone hits the water 3.41 m in front of the raft. Find the speed of the raft.
A woman on a bridge 91.1 m high sees a raft floating at a constant speed on the river below. She drops a stone from rest in an attempt to hit the raft. The stone is released when the raft has 5.59 m more to travel before passing under the bridge. The stone hits the water 3.55 m in front of the raft. Find the speed of the raft.
A woman on a bridge 91.9 m high sees a raft floating at a constant speed on the river below. She drops a stone from rest in an attempt to hit the raft. The stone is released when the raft has 5.62 m more to travel before passing under the bridge. The stone hits the water 2.61 m in front of the raft. Find the speed of the raft.
A projectile is launched at 59.5 m/s from a height of 83.5m, at the edge of a sheer cliff. The projectile falls, just missing the cliff and hitting he ground below. Find the time it takes to hit the ground at the base of the cliff.
A woman on a bridge 74.1 m high sees a raft floating at a constant speed on the river below. She drops a stone from rest in an attempt to hit the raft. The stone is released when the raft has 7.13 m more to travel before passing under the bridge. The stone hits the water 3.91 m in front of the raft. Calculate the speed of the raft.
The great, gray-green, greasy Zambezi River flows over Victoria Falls in south central Africa. The falls are approximately 107 m high. If the river is flowing horizontally at 3.70 m/s just before going over the falls, what is the speed of the water when it hits the bottom? Assume the water is in free fall as it drops. HW 4.4 Problem Solving 4.84 7 of 7 Constants PartA The great, gray green, greasy Zambezi River flows over Victoria Falls in...
A man of mass m is standing on a bridge h meters high. The man is l m tall and he has a bungee chord attached to him that is L m long. The man bungee jumps of the bridge so that he just "kisses" the water below. The chord stretches x m. Form an equation for the height. (hint: you will use the quadratic equation and spring constant)
You throw a small rock straight up from the edge of a highway bridge that crosses a river. The rock passes you on its way down, 5.00 s after it was thrown. What is the speed of the rock just before it reaches the water 27.0 m below the point where the rock left your hand? Ignore air resistance.
