Question

Can I have the answer please

answer in the form of a question, to the statement below

1-"The length of an arrow is used to represent this, in a vector"

2.An airplane making an approach for landing decelerates at a rate of 2m/s2. How long will it take the airplane to reduce its speed by 264km/h

Answer 1

ANSWER: Length of an arrow is used to represent magnitude in a vector

------------------------------------

deceleration =2m/s²

Given reduction in speed as 264km/hr

Convert it into m/s

$264km/hr=73.3m/s$

so initial speed - final speed =73.3 m/s

$u-v=73.3m/s$

Use Formula $v=u+at$

$v-u=at$

$u-v=-at$

$73.3m/s=-*-2m/s^{2}*t$

$73.3=2*t$

ANSWER: $t =36.65s$
