Can two objects of different masses have the same acceleration and speed?

Yes

Explanation:

It's like when you drop two different masses out of a window, to example a bag and a soda bottle, they both will hit the ground at the same time as long as there isn't a huge difference in resistance like paper and a brick, those would not hit at the same time. Or to be simpler, a truck and a minivan are different masses but both can have the same acceleration and speed.

explanation:

a fuel engine ( known as a gasoline engine in american english )is an internal combustion engine with spark ignition, designed to run on petrol (gasoline) and similar volatile fuels.

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
