. A projectile is thrown into space so as to have maximum


possible range of 400m . Taking the point of projection as the origin, the coordinate of the point where the velocity of the projectile is minimum is

A: (400,100)

B: (200,100)

C: (400,200)

D: (200,200)

 

Best Answer

Explanation:

Maximum possible Range Rmax=400m

Maximum height attained H=Rmax/4 =100m

The particle has maximum velocity at top on point of its projectile is

Motion whose coordinate (Rmax/2,H)

So X coordinate X= 400/2=200m

Y coordinate Y = H= 100m

Final Answer:

Hence, the correct option is (B)  (200,100)
