Document -Word Compress Pictu ] Haight: 3.ce' range Our goal is to use this video to measure the acceleration of the space shuttle Endeavor as it moves the first 62 meters after liftoff What is the last frame before the shuttle begins to move? (Do not enter units for this answer.) 142 At what frame has the shuttle traveled 62 meters? (Do not enter units for this answer.) 248 What is the elapsed time? 4.42 s Assuming constant acceleration, at what rate is the shuttle accelerating? Enter a number with units. If the shuttle continued to move with this acceleration, what speed would it reach 20 s after launch? If the shuttle traveled directly upwards, what would its altitude be at 20 s? XUnits are required for this answer

Explanation / Answer

distance, d=62 m ,

elapsed time, t=4.42 sec

d)

use,

d=u*t + 1/2*a*t^2

62=0+1/2*a*4.42^2

==> acceleration, a=6.35 m/sec^2 ----> answer

e)

use,

v=u+a*t

v=0+6.35*20

===> v=127 m/sec -----> answer

f)

distance travelled upwards,

d=u*t+1/2*a*t^2

d=0+1/2*6.35*20^2

d=1270 m ----> answer
