During launches, rockets often discard unneeded parts. A certain rocket starts from rest on the launch pad and accelerates upward at a steady 3.15 m/s2 . When it is 245 m above the launch pad, it discards a used fuel canister by simply disconnecting it. Once it is disconnected, the only force acting on the canister is gravity (air resistance can be ignored). Part A How high is the rocket when the canister hits the launch pad, assuming that the rocket does not change its acceleration?     y=    m Part B What total distance did the canister travel between its release and its crash onto the launch pad?   d=    m

Question

During launches, rockets often discard unneeded parts. A certain rocket starts from rest on the launch pad and accelerates upward at a steady 3.15 m/s2 . When it is 245 m above the launch pad, it discards a used fuel canister by simply disconnecting it. Once it is disconnected, the only force acting on the canister is gravity (air resistance can be ignored).

Part A

How high is the rocket when the canister hits the launch pad, assuming that the rocket does not change its acceleration?
 
 
y=    m

Part B

What total distance did the canister travel between its release and its crash onto the launch pad?
 
d=    m
