Question

a ball is dropped from height 100km.calculate the magnitude

Answer 1

Whose magnitude your question is incomplete

Answer 2

Magnitude means the speed of an object.Therefore,,

v = √2hg {g = 9.8 m/s²}

v = √2×100×10³×9.8

v = √19600×10²

v = 1400 m/s

So, the magnitude must be 1400 m/s. Hope, it was helpful.
