The velocity of a particle moving in the positive direction of x-axis varies as v = α√x where α is positive constant. If at t = 0, x = 0, the velocity and acceleration as a function of time t will be the velocity and acceleration as a function of time t will be The [...]

The deceleration experienced by a moving motorboat after its engine is cut-off, is given by dt/dv ​= − kv^3 where k is constant. If v0​ is the magnitude of the velocity at cut-off, the velocity v at a time t after the cut-off will be is given by dt/dv ​= − kv^3 where k is [...]
