A train 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? Neglect air resistance.

A 361 m

B 330 m

C 256 m

D 146 m

E 166 m

Answer #1

t= 2v/g

t= 2x9.8/9.8 = 2 sec.


x= vx*t

x= 83x2 = 166 m.
