Answer:
In 2.748 sec the mailbag reached the ground
Explanation:
We have given height from the ground
At t =2.25 sec helicopter releases a small mailbag so at t = 2.25 sec height from the ground
When the mail box is drooped its initial velocity would zero so u = 0 m/sec
Acceleration due to gravity
According to third law of motion
t = 2.748 sec
Answer:
Distance travelled: 20meters
Displacement: 10 meters.
Explanation:
In geometry and mechanics, a displacement is a vector whose length is the shortest distance from the initial to the final position of a point P undergoing motion. It quantifies both the distance and direction of the net or total motion along a straight line from the initial position to the final position of the point trajectory. A displacement may be identified with the translation that maps the initial position to the final position.
