Homework SourseA particle moves on a number line with acceleration starting
A particle moves on a number line with acceleration, starting from rest. For the interval from t=0 to t=2, Find the net change in position and the total distance the particle travels.
A particle moves on a number line with acceleration, starting from rest. For the interval from t=0 to t=2, Find the net change in position and the total distance the particle travels.
Solution
Total distance the particle travels is
s = ut + ( 1/ 2 ) g t2
initial velocity u = 0. so,
s = ( 1/ 2) g t2
= ( 1 /2 ) ( 9.8 m/s2 ) ( 2 s )2
=19.6 m
