QuestionA train stops and speeds up to $60 \mathrm{~m/s}$ in $40 \mathrm{~s}$ . Find its acceleration. A boat stops in $6 \mathrm{~s}$ from $18 \mathrm{~m/s}$ . Find its acceleration.

Studdy Solution
Calculate the acceleration.
$a = \frac{-18 \, m/s}{6 \, s} = -3 \, m/s^2$ The acceleration (actually, deceleration) of the boat is $-3 \, m/s^2$ .
