Question

a body of mass m is taken to a height R from the surface of the earth and then is given horizontal velocity v,the minimum value of v so that the body never returns to the surface of earth
​

Answer 1

Explanation:

velocity will be 0

because

1/2×m×v×v

1/2×m×0×0

1/2×m×0

1/2×0

=0

then there will be no displasment when it cant returens to earth surface

Answer 2

Answer:

hopefully it will work ☺️☺️
