Question

An object is projected at an angle of elevation of 45 degree with a velocity of 100 m/s. Calculate its
(i) range
(ii) time of flight
answer in above 40 words

Answer 1

range = u^2 x sin 90 / g
= 2 x 10000 x 1 / 10
= 2000 m

time of fight =( 2 x 100 x 1 ) 10 x root 2
t = 20 / root 2
t= 14.14 sec
