Answer:8730.63 m
Explanation:
Given
Bomber velocity relative to ground
Altitude of the bomber
Range of bomb when bomb when it is released is given by
where
Horizontal velocity of bomber is equal to bomb horizontal velocity
time taken by to cover 3580 m
Therefore range of bomb is
Therefore bomber must release the bomb at a horizontal distance of 8730.63 m before the hit point
Answer:
Both the cases deal with the principle of pressure due to force acting on an area.
Explanation:
When a stone is place between a pile of book and our head when we carry it then the area subjected to the force decreases while the magnitude of the force remains same and therefore the pressure on our head increases.
As we know that pressure is force per unit area is called pressure.
Mathematically:
It is easy to cut our skin with an edge of a paper because our skin is relatively softer than the edge of a paper and the edge of a paper is thin which applies more pressure due to less area of contact with our skin.
Answer:
|v|=2.98m/s
Explanation:
In order to solve this problem we must first draw a diagram that will represent the situation. (See picture attached)
In this case the boat is being dragged by the river while it has a given velocity relative to the water and perpendicular to the flow of the river. We can take these velocities as vectors so we can add them up:
which yields:
|v|=2.98m/s
so an observer that is stationary on the shore will se the boat having a speed of 2.98m/s.
