Dear Shivam
initial upward velocity u=100/√2 m/s
at highest point velocity is zero
using v2=u2-2gH
put v=0
H=u2/2g = 10000/(2x2x10)= 250m
All the best.

range of projectile = u2sin2@/g = u2/g (at @=45)
it forms a semicircle in sky so this range is equal to diameter of this circle...
now , D = u2/g
D =2R (R is radius of semicircle)
R = u2/2g
maximum height will be radius of this semicircle
Hmax = u2/2g=500m
hello ,
since the formula for height of a projectile is u2sin2angle/2g, the answer can be calculated thus...
since it makes a semi circle in skymax height is half of i t's range
range R=U2SIN2(ANGLE)/g
100*100/10
=1000
then its max.height =500
the ball will undergo a projectile motion. the formula for the max. height attained by the ball is =u^2cos^theta/2g
theta=45 deg
u=100m/s g=10m/s^2
therefore
H=10000*0.5/2*10
=250m
