Question

Pls help

A spacecraft leaves the solar system at a velocity of 1,500 m/s. The net force on

this spacecraft is zero. What can we say about the spacecraft's acceleration?


A. It must be zero


B. It has to be slightly positive or the spacecraft will slow down and stop.


C. It has to be slightly negative or the spacecraft will slow down and stop.


D. We don't know the acceleration without more data.

Answer 1

A. It must be zero

Step-by-step explanation:

A spacecraft leaves the solar system at a velocity of 1,500 m/s. The net force on this spacecraft is zero. What can we say about the spacecraft's acceleration?

According to Newton's second law

Force = Mass × acceleration

If the net force is zero

0 = mass × acceleration

0 = ma

a = 0/m

a = 0m/s²

this shows that the acceleration will be zero If the net force is zero
