4.10 A body of mass 0.40 kg moving initially with a constant speed of

10 \mathrm{~m} \mathrm{~s}^{-1}

to the north is subject to a constant force of 8.0 N directed towards the south for 30 s . Take the instant the force is applied to be

t=0

, the position of the body at that time to be

x=0

, and predict its position at

\mathrm{t}=-5 \mathrm{~s}, 25 \mathrm{~s}, 100 \mathrm{~s}

. (1) Predict its position at t=-5 s. (2) Predict its position at 25 s. (3) Predict its position at 100 s.
