Question

a)A plane flying horizontally at 100m/s at height 1000m releases a bomb from it. Find 1) the time it takes to reach the ground 2) the velocity with which bomb hits the target in the ground. 3)find the distance​

Answer 1

Answer:

Find 1) the time it takes to reach the ground 2) the velocity with which bomb hits the target in the ground. b) while firing one has to aim a little above the target and ...

Answer 2

Answer:

mark as brainlist please

Explanation:

1. Using Newton's law of motion,

s = ut + (1/2) * a * t^2

1000 = (1/2) * 10 * t^2 [ taking acceleration due to gravity to be 10 m/s^2]

t = 10 \sqrt{2}

2

sec

2. Using Newton's law of motion,

v = u + at

v = 10 * 10 \sqrt{2}

2

v = 100 \sqrt{2}

2

m/s

3. One has to aim a little above the target and not exactly on the target while firing to account for the vertical displacement caused by acceleration due to gravity.
