Question
A military helicopter on a training mission is flying horizontally at a speed of 90.0m/s when it accidentally drops a bomb (fortunately, not armed) at an elevation of 390m . You can ignore air resistanceHow much time is required for the bomb to reach the earth?
How far does it travel horizontally while falling?
Find the horizontal component of the bomb's velocity just before it strikes the earth.
Find the vertical component of the bomb's velocity just before it strikes the earth.
If the velocity of the helicopter remains constant, where is the helicopter when the bomb hits the ground?
A daring 51kg swimmer dives off a cliff with a running horizontal leap, as shown in the figure below.
What must her minimum speed be just as she leaves the top of the cliff so that she will miss the ledge at the bottom, which is L= 2.40m wide and h= 9.10m below the top of the cliff?
A football is thrown with an initial upward velocity component of 12.5m/s and a horizontal velocity component of 17.0m/s .
How much time is required for the football to reach the highest point in its trajectory?
How high does it get above the ground?
How much time after it is thrown does it take to return to its original height?
How far has the football traveled horizontally from its original position?
A boy 11.0m above the ground in a tree throws a ball for his dog, who is standing right below the tree and starts running the instant the ball is thrown. If the boy throws the ball horizontally at 8.00m/s .
How fast must the dog run to catch the ball just as it reaches the ground?
How far from the tree will the dog catch the ball?
A boy 14.0m above the ground in a tree throws a ball for his dog, who is standing right below the tree and starts running the instant the ball is thrown. If the boy throws the ball upward at 65.0degrees above the horizontal, at 8.00m/s
How fast must the dog run to catch the ball just as it reaches the ground?
How far from the tree will the dog catch the ball?
