Atrain is moving with a constant velocity of 83 m/s in the easterly direction.

a girl on the train looks out the window and sees a boy outside with a toy rocket.

the boy fires the rocket with an initial velocity of 9.8 m/s straight up into the air.

how far does the train travel in the easterly direction while the toy rocket is in the air, i. e. how far does the train travel during the time it takes the rocket to go up and back down to the ground again?

166 m

Explanation:

t = Time taken

u = Initial velocity = 9.8 m/s

v = Final velocity

s = Displacement

g = Acceleration due to gravity = 9.80 m/s² = a

Equation of motion

Time taken to go up is 1 second and to go down will also be 1 second

Total time the rocket is up in the air is 2 seconds

The distance the train will travel is 166 m

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.
