A bullet of mass 20 g has an initial speed of 1 ms^−1, just before it starts penetrating a mud wall of thickness 20 cm. if the wall offers a mean resistance of 2.5 × 10^−2 N, the speed of the bullet after emerging from the other side of the wall is close to : [...]

A ball is thrown upward with an initial velocity V0​ from the surface of the earth. The motion of the ball is affected by a drag force equal to mγv2 (where m is mass of the ball, v is its instantaneous velocity and γ is a constant). Time taken by the ball to rise to [...]

The position of a particle as a function of time t, is given by x(t) = at + bt^2 − ct^3 where a, b and c are constants. When the particle attains zero acceleration, then its velocity will be b and c are constants. When the particle attains zero acceleration is given by x(t) = [...]

A particle starts from origin O from rest and moves with a uniform acceleration along the positive x-axis. Identify all figures that correctly represent the motion qualitatively. (a = acceleration, v = velocity, x = displacement, t = time) A particle starts from origin O from rest and moves with a uniform acceleration along the [...]
