When a ball is thrown up vertically with velocity u it attains a maximum height h What should be the velocity so that maximum height becomes 2h?
Thus maximum height attained becomes four times (4H) when the initial velocity is increased by 2 times.
When a ball thrown up with velocity v0 it reaches the maximum height then the ball should thrown with?
When a ball is thrown up vertically with velocity v0, it reaches a maximum height of h. If one wishes to triple the maximum height then the ball should be thrown with velocity.
What is the final velocity of a body moving against gravity when it attains the maximum height?
When it reaches the maximum height? When we throw a ball upwards then g is negative because body is moving against gravity and Its final velocity i.e when it reached maximum height ,its velocity is zero.
When a body is thrown up vertically with an initial velocity then?
A body is thrown vertically upwards with an initial velocity u reaches the maximum height in 6s. The ratio of the distance traveled by the body in first second to seventh second is. Since the paticle reaches maximum height in 6 s, at 7th second travel, its initial velocity is zero.
How is universal gravitational constant calculated?
In Newton’s law of universal gravitation, the attractive force between two objects (F) is equal to G times the product of their masses (m1m2) divided by the square of the distance between them (r2); that is, F = Gm1m2/r2.
When a body projected vertically the maximum height of it is?
Note: In vertical projectile motion, the velocity of the body at its maximum height becomes zero.
When a body is projected vertically up from the ground its velocity is reduced to?
when a body is projected vertically up from the ground its velocity is reduced to 1/4th of its velocity at ground .
When a body is projected vertically up at a point P in its path?
When a body is projected upwards then at the highest point or the maximum height of its journey, its velocity becomes zero and thus its kinetic energy also becomes zero. At this point, the body only has potential energy (which is at its maximum value) due to the force of gravity acting on it.
When a body is projected vertically upwards the direction of acceleration is?
For a vertically upward thrown ball, gravitational force always acts downward. That is why the body will experience a negative acceleration on its upward journey. The value will be same as gravitational acceleration.
What happens to a body when it is projected vertically?
11200 m/s = 11.2 km/s is the Escape Velocity for Earth. Any object projected vertically upwards at this speed can escape the gravity of the Earth and reach into space.
