1.	12. Figure shows four paths for a kicked football. Ignoring theeffects of air on the flight, rank the paths according to initialhorizontal velocity component, highest first(a) 1, 2, 3, 4(c) 3, 4, 1, 2(b) 2, 3, 4, 1(d) 4, 3, 2, 1
Answer» considering the motion to be projectile maximum height is u²sin²∅/2g so, if maximum height is same for all , and if ∅ is increased , the velocity should be reduced , to maintain the same height so, 4 has less angle.. and 1 has maximum angle => velocity order is 4>3>2>1 option d

Answer»

considering the motion to be projectile

maximum height is u²sin²∅/2g

so, if maximum height is same for all , and if ∅ is increased , the velocity should be reduced , to maintain the same height

so, 4 has less angle.. and 1 has maximum angle

=> velocity order is 4>3>2>1

option d
