[Young & Freedman, 3-12] A military airplane on a routine training mission is flying horizontally (in the positive x-direction) at a speed of 120. m/s and accidently drops a bomb (fortunately not armed) at an elevation of 2090 m. Air resistance may be ignored and answer with the appropriate number of significant figures.
a) How much time is required for the bomb to reach the earth? 1 s
b) How far does the bomb travel horizontally while falling? 2 m
c) Find the horizontal component of the velocity of the bomb just before it strikes the earth. (Include a negative sign if the velocity is in the negative direction. Do not include any sign if the velocity is in the positive direction.) 3 m/s
d)Find the vertical component of the velocity of the bomb just before it strikes the earth. (Include a negative sign if the velocity is in the negative direction. Do not include any sign if the velocity is in the positive direction.) 4 m/s
e) How far does the airplane travel while the bomb is in the air if the airplane's speed remains constant? 5
a) You should know how long it takes to fall a distance of 2090 m?
Think about using the equation y = (g/2) t^2
b) Multiply the time from (1) by 120 m/s
c) The horizontal component does not change. Why woujld it become negatve?
d) Vy = -g*t. Use the t from (1)
e) Same as (b)
You should do some thinking of your own. These are not hard questions.
