A projectile is fired from a gun at an angle of 45º with the horizontal and with a speed of 20 m/s relative to ground. At the highest point in its flight the projectile explodes into two fragments of equal mass. One fragment comes at rest just after explosion. How far from the gun does the other fragment land, assuming a horizontal ground ? Take g = 10 m/s 2 ?
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
60m.
Sol. X cm = 
= 
= 40 m.
x 1 = 
= 20 m ⇒ x cm = 
⇒ 40 = 
get x 2 = 60 m
