Question

a rocket traveling at 31 m/s Fars it’s retrorockets generating a negative acceleration. The Rockets are fired for 17 seconds afterwards the rocket is traveling at 22 m/s what is the Rockets acceleration?

Answer 1

-0.52 m/s^2

Step-by-step explanation:

Givens: v1= 31m/s v2= 22m/s t=17s a=??

v2= v1 + a*t

22 m/s - 31m/s= a*t

22 m/s - 31m/s/17s=a

=-0.52m/s^2 or -9/17 m/s^2
