Answer: 1) t=0.5 s; S=6.225 m and v=14.9 m/s
2) t=1 s; S=14.9 m and v=19.8 m/s
3) t=1.5 s; S=26.05 m and v=24.7 m/s
Explanation:
The displacement is given by
and final velocity is given by
where is the initial velocity
is acceleration
is time taken
Case 1: when time is 0.5 s
The displacement is
the velocity is
Case 2: when t=1 sec
The displacement is
the velocity is
Case 3: t=1.5 s
The displacement is
the velocity is
