Question

equation of trajectory of projectile projected from origin is given by y=100x-25x2 . what will be the range of projectile?
a) 2500 m
b) 40m
c) 4m
d) 100 m
​

Answer 1

Answer:

ANSWER

y=−x2+10x

Comparing with Standard equation of trajectory y=tanθx−2u2cos2θgx2

We get tanθ=10 and 2u2cos2θg=1

cosθ=1011

u=505m/s
