A particle of mass 2m is projected at an angle of 45^(@) with the horizontal with a velocity of 20sqrt(2)m//s, After 1s of explosion, the particle breaks into two equal pieces. As a result of this one part comes to rest. The maximum height from the ground attained by the other part is n xx 7m. Find n (g = 10ms^(-2))

1.	A particle of mass 2m is projected at an angle of 45^(@) with the horizontal with a velocity of 20sqrt(2)m//s, After 1s of explosion, the particle breaks into two equal pieces. As a result of this one part comes to rest. The maximum height from the ground attained by the other part is n xx 7m. Find n (g = 10ms^(-2))
