Problem

a. A space probe has a mass of

1.2\times10^{3}\,\text{kg}

and experiences a steady thrust that gives it an acceleration of

3.5\,\text{m\,s}^{-2}

. Calculate the magnitude of the thrust in scientific notation. b. Later, the probe's mass decreases to

8.0\times10^{2}\,\text{kg}

while the thrust remains the same. Determine its new acceleration.
