Question

A rocket is fired vertically upwards with an acceleration 10 m/s2 . To what maximum heights would the rocket rise if its fuel gets exhausted in 1 min?

Answer 1

Answer:

Explanation:

S=ut=  1/2at^2

S=  1/2  

(10) (30^2)

=4500m

v^2+u^2=2as

v=300m/s

​  

 

now after fuel is consumed

a=−10

v=0

v=u−gt

t=30s

totaltime=30+30=60s
