Question
(The picture shows the full question.)
Where are you? A particle’s position r in time t was shown to be:
r(t) = (t + sin t)ˆi + (t)ˆj + (2.00 [m]) kˆ.
What is it’s velocity v and acceleration a at t = 5.00 [s]?
A. v = (1.00 [m/s])ˆj,
a = (0.0871 [m/s^2])ˆi
B. v = (1.28 [m/s])ˆi+(1.00 [m/s])ˆj,
a = (0.959 [m/s2])ˆi
C. v = (2.00 [m/s])ˆi−(0.09 [m/s])ˆj,
a = (−0.959 [m/s2])ˆi
D. v = (0.72 [m/s])ˆi+(1.00 [m/s])ˆj,
a = (−0.959 [m/s2])ˆi
