A ball is thrown with velocity `V_0` from ground in vertical upward direction, if particle experiences resistance force `mkv^2` . where v is the speed of particle, m mass of the particle and k is a positive constant. Find maximum height reached.

A small ball of mass m is thrown upward with velocity u from the ground. The ball experiences a resistive force mkv^(2) where v is its speed. The maximum height attained by the ball is :

Assuming the gravity to be in negative z-direction, a force F=vxxA is exerted on a particle in addition to the force of gravity where v is the velocity of the particle and A is a constant vector in positive x-direction. With what minimum speed a particle of mass m be projected so that it continues to move undeflected with constant velocity ?

A particle is projected from ground with speed u and at an angle theta with horizontal. If at maximum height from ground, the speed of particle is 1//2 times of its initial velocity of projection, then find its maximum height attained.

A ball is thrown upward with an initial velocity V_0 from the surface of the earth.The motion of the ball is affected by a drag force equal to mgammav^2 (where m is mass of the ball, v is its instantaeous velocity and gamma is a constant).Time taken by the ball to rise to its zenith is :

A particle having a velocity v = v_0 at t= 0 is decelerated at the rate |a| = alpha sqrtv , where alpha is a positive constant.

A particle is projected from a stationary trolley. After projection, the trolley moves with a velocity 2(sqrt15) m//s . For an observer on the trolley, the direction of the particle is as shown in the figure while for the observer on the ground, the ball rises vertically. The maximum height reached by the ball from the trolley is h meter. The value of h will be .......... .

A particle is thrown upwards from ground it experiences a constant resistance force which can produce retardation of 2m/s^2 The ratio of time of ascent to the time to descent is (g=10m/s^ 2)

The velocity of a particle moving in the positive direction of the X-axis varies as V=Ksqrt(S) where K is a positive constant. Draw V-t graph.
