Question

Hey friends please answer this question it's urgent and please help me in solving projectile problems..

Answer 1

Hello student,
Convert velocity in horizontal direction, Ux into m/s:
Ux = 600x1000/3600 = 500/3 m/s
Velocity of the bomb during the flight is constant due to inertia. Therefore,
Initial velocity in vertical direction, Uy = 0
Height = 1960 m
Step 2: Find time ‘t’ using the equation [s = ut + 1/2at^2]
Replace distance ‘s’ by height ‘h’ and acceleration ‘a’ by gravity ‘g’
h = 1/2gt^2
t = √(2h)/g = √(2x 1960/9.8) = 20 sec.
Step 3: Find the distance traversed by the bomb in horizontal direction:
Distance AB = vx t = 500/3 x 20 = 10/3 x 10^3m = 3.333 km.
Thanks and Regards
