Who Knows The Answer??

A toy rocket is launched vertically from ground level (y = 0 m), at time t = 0.0 s. The rocket engine provides constant upward acceleration during the burn phase. At the instant of engine burnout, the rocket has risen to 64 m and acquired a velocity of 90 m/s. The rocket continues to rise in unpowered flight, reaches maximum height, and falls back to the ground.

The upward acceleration of the rocket during the burn phase is closest to:

a) 61 m/s2

b) 59 m/s2

c) 58 m/s2

d) 63 m/s2

e) 56 m/s2

i didn't even read the whole question but i'm going to take a random guess and go with (b).

 

[fsscott]

so its always gonna be the middle ones so i would guess (c)

Write- z) Test Failiure, rocket came to complete stop when it rammed (Insert teachers name here) up the ass and exploded, RIP teacher.

hahaha

 

[An10a_Eng]

seriously? that is probably one the easiest physics questions ive ever seen in my life

 

[bikerocker]

when in doubt charlie out....

 

[Edew19]

d

vf^2=vo^2+2a(y-yo)

 

[Malcolm]

come on guys be serious this isnt rocket sience. or is it....

 

[12ParkRat60]

lol..

 

[tigon]

v^2 = vi^2 + 2ad

vi=0 so you can cancel it

so... v^2 = a

2d

90^2 = 63m/s^2

2(64)

ahhhhhhh i hate physics

 

[Canuker]

Lmao

 

[doublexl]

C.

C is the most common answer

always go with C if you dont know the answer.

thanks man that's what i got

 

[squaw_skier]

its d

and why do you have a thread about a math question? just curious

 

[Sno.]

tis his homework

 

[jack_weisman]

cause he doesn't know the answer...

 

[ShredTheGnarnia]

haha wow thanks for answering i was wondering the same thing!!!! rofl waffles
