A particle is projected with velocity $\vec{v} = (6\hat{i} + 8\hat{j})$ m/s. If $g = 10 m/s^2$, the radius of curvature of its trajectory at the highest point is:

A projectile is launched with an initial velocity $v_0$ at an angle $heta$ with the horizontal. At the highest point of its trajectory, the ratio of its potential energy to its kinetic energy is:

A projectile is launched with velocity $v$ at an angle $heta$ to the horizontal. At the highest point of its trajectory, it explodes into two equal fragments. One fragment falls vertically downwards with zero initial speed. What is the distance from the point of projection where the other fragment lands?

A ball is thrown horizontally from a cliff edge with velocity $v$. Another ball is dropped vertically from the same point at the same instant. Neglecting air resistance, which statement is TRUE about the time taken for each ball to reach the ground below?

A projectile is launched horizontally with speed $v$ from a height $h$. If another projectile is launched horizontally from the same height with speed $2v$, how does the horizontal range of the second projectile compare to the first?

A projectile is launched horizontally from a height $h$ with velocity $v$. At what angle below the horizontal will the velocity vector be pointing when the projectile has fallen a vertical distance of $h/2$?

Two projectiles A and B are launched horizontally with velocities $v$ and $2v$ respectively from the same height $h$. If projectile A lands at a horizontal distance $x$ from the launch point, at what horizontal distance will projectile B land?

A stone is projected horizontally with a velocity $v$ from the top of a tower of height $h$. At the same instant, another stone is dropped vertically from the same point. Which of the following graphs correctly represents the variation of the relative speed ($v_r$) between the two stones with time ($t$) until the first stone hits the ground?

A ball is thrown at an angle of 30 degrees with the horizontal. At what point in its trajectory is the vertical component of its velocity zero?

A projectile is launched at an angle $heta$ with the horizontal. If its initial velocity is $v_0$, what is its horizontal range?
