I need help with (Second: Motion of the fired bomb)

Second: Motion of the fired bomb:
The tank is to be placed on a hill that is 1 km high above the ground. The enemy's base is located at a horizontal
distance of 10 km away and it is in a valley 0.5 km below the ground. Air resistance is neglected. Gravitational
acceleration is constant and equal to 9.8m/s2 downwards.
a) If the bomb is to be fired perfectly horizontally, what should the launching speed of the bomb be in order to
hit the target?
b) What is the duration it would take the bomb to hit the target?
c) Find x(t) and y(t). Consider the initial location of the tank to be (0, 1 km)?
d) Draw the trajectory of the bomb (x and y coordinates). Indicate clearly the value of x (horizontal
displacement) when the bomb reaches the ground level.
e) Draw the y(t), vy(t), and ay(t) vertical above each other. Indicate key values on the graphs such as the
start, the end, the maximum, the minimum and the x and y intercepts.

Expert Solution

Step 1

Since there are many sub-parts, we’ll answer the first 3 sub-parts as you have not mentioned the sub-parts you need help with. Please resubmit the question and specify the other sub-parts you would like to get answered.

b) Duration taken by the bomb to hit the target

The vertical velocity of bomb is initially zero, because the bomb was launched horizontally. Using kinematic equation, the expression for distance covered by the bomb vertically is

Step 2

Rewriting the above equation to find the time period and plugging the values then the duration taken by the bomb to hit the target would be
