An aircraft carrier is sailing at a constant speed of 15.0m/s. it is suddenly spotted by an enemy bomber aircraft flying in the same direction as the ship is moving. the bomber is flying at a constant speed of 100 m/s at an altitude of 1.00 km above the carrier when it decides to attack the carrier. if the bomber drops its bomb at a horizontal distance pf 1.3 km from the aircraft carrier, will it score a direct hit?

Explanation:
Relative velocity = 100 - 15 = 85 m /s
Distance to be covered up with this relative speed = 1.3km
= 1300m
If t be the time taken
85 x t = 1300
t = 1300/ 85
= 15.29
Time of fall of the bomb t₁ by 1 km
1000 = 1/2 g t₁²
t₁² = 2000/9.8
t₁ = 14.28 s
Since t₁≠ t₂
It will not score a direct hit.
Ответ:
the potential energy is higher as the object when it falls will have more room to accelerate using kinetic energy
