use formula
Range=u^2sin2@/g
time of flight =2usin@/g
where u is the initial velocity, @ is angle of elevation of the velocity and g is the acceleration due to gravity.
now
Range=(100)^2sin90/10=1000m
time of flight =2 x 100 x sin45/10=10root2
Range=u^2sin2@/g
time of flight =2usin@/g
where u is the initial velocity, @ is angle of elevation of the velocity and g is the acceleration due to gravity.
now
Range=(100)^2sin90/10=1000m
time of flight =2 x 100 x sin45/10=10root2
