Aplane drops a hamper of medical supplies from a height of 2830 m during a practice run over the ocean. the plane’s horizontal velocity was 106 m/s at the instant the hamper was dropped. what is the magnitude of the overall velocity of the hamper at the instant it strikes the surface of the ocean? the acceleration of gravity is 9.8 m/s 2 . answer in units of m/s.

Overall velocity will be 258.27 m/sec  

Explanation:

We have given height = 2830 m

Acceleration due to gravity

Horizontal velocity

From third equation of motion

As the hamper is drooped so u=0

Overall velocity is given by

So overall velocity will be 258.27 m/sec

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
