Question
A military helicopter on a training mission is flying horizontally at a speed of 60.0m/s when it accidentally drops a bomb (fortunately, not armed) at an elevation of 500m . You can ignore air resistance. Part A How much time is required for the bomb to reach the earth? t = s Part B How far does it travel horizontally while falling? L = m Part C Find the horizontal component of the bomb's velocity just before it strikes the earth. vx = m/s A military helicopter on a training mission is flying horizontally at a speed of 60.0m/s when it accidentally drops a bomb (fortunately, not armed) at an elevation of 500m .

T=sqrt(2*H/g)=sqrt(2*500/10)=10 s
Distance traveeled = u*T=60*10=600 m
The horizontal component of the bomb doesnt change. So Vx= 60 m/s
