Answer 1

55-23/3=10.66 m/s^2

Answer 2

im sorry i need it in ft/s^2

Answer 3

divide the change in velocities with the time taken

Answer 4

do you how to change ft to meters?

Answer 5

v=u+at
v-u=at
\[a=\frac{ v-u }{ t }\]

Answer 6

i need feet. i have to convert feet to meters.?

Answer 7

55m/h=\[55m/hr=\frac{ 55*1760*3 }{ 1*60*60 }=? ft/\sec\]

Answer 8

80.6666 repeating 6's

Answer 9

1 mile=1760 yards
