Step 1
First, we need to find the initial horizontal and vertical components of the velocity. The horizontal component of the velocity (u_x) is given by u_x = u * cos(θ), where u is the initial velocity and θ is the angle of projection. The vertical component of the Show more…

A body of mass $0.5 \mathrm{~kg}$ is projected under gravity with a speed of $98 \mathrm{~m} / \mathrm{s}$ at an angle of $30^{\circ}$ with the horizontal. The change in momentum (in magnitude) of the body is (a) $24.5 \mathrm{~N}-\mathrm{s}$ (b) $49.0 \mathrm{~N}-\mathrm{s}$ (c) $98.0 \mathrm{~N}-\mathrm{s}$ (d) $50.0 \mathrm{~N}-\mathrm{s}$
A particle is projected with a speed of $40 \mathrm{~m} / \mathrm{s}$ at an angle of $60^{\circ}$ with the horizontal. At what height speed of particle becomes half of initial speed $\left(g=10 \mathrm{~m} / \mathrm{s}^{2}\right)$. (A) $30 \mathrm{~m}$ (B) $45 \mathrm{~m}$ (C) $37.5 \mathrm{~m}$ (D) $60 \mathrm{~m}$
A particle moves in the $x-y$ plane under the influence of a force such that its linear momentum is $\vec{p}(t)=A$ $[\hat{i} \cos (k t)-\hat{j} \sin (k t)]$, where $A$ and $k$ are constants. The angle between the force and the momentum is (a) $0^{\circ}$ (b) $30^{\circ}$ (c) $45^{\circ}$ (d) $90^{\circ}$
