The position of a particle is given by;
\(\overrightarrow{r}=(3.0t\hat{i}-2.0t^{2}\hat{j}+4.0\hat{k})\) m
where \(t\) is in seconds and the coefficients have the proper units for \(r\) to be in meters. The magnitude and direction of \(\overrightarrow{v}(t)\) at \(t=1.0\) s are:
1. | \(4\) m/s \(53^\circ\) with \(x\)-axis |
2. | \(4\) m/s \(37^\circ\) with \(x\)-axis |
3. | \(5\) m/s \(53^\circ\) with \(y\)-axis |
4. | \(5\) m/s \(53^\circ\) with \(x\)-axis |
