141215 A person sitting in the ground floor of a building notices through the window of height \(1.5 \mathrm{~m}\), a ball dropped from the roof of the building crosses the window in \(0.1 \mathrm{~s}\). What is the velocity of the ball when it is at the topmost point of the window? \(\left(g=10 \mathrm{~m} / \mathrm{s}^{2}\right)\)

141216 A particle starts from the origin with an initial velocity \(\overrightarrow{\mathbf{u}}=(3.0 \hat{\mathbf{j}}) \mathrm{m} / \mathrm{s}\) and a constant acceleration \(\overrightarrow{\mathbf{a}}=(-0.5 \hat{\mathbf{i}}-\mathbf{1 . 0} \hat{\mathbf{j}}) \mathrm{m} / \mathrm{s}^{2}\). The velocity of the particle when it reaches its maximum y coordinate is:

141217 An object is moving in a plane and its trajectory \(\overline{\mathbf{r}}(\mathbf{t})\) (in meter) is given by, \(\overline{\mathbf{r}}(t)=\left(3 t^{2}+2 t\right) \hat{\mathbf{i}}+2 t \hat{\mathbf{j}}\), where \(t\) is time (in second). The angle that the velocity vector makes with the \(X\)-axis at \(t=0\).
