For motion of an object along the x-axis, the velocity v depends on the displacement x as v = 3x^2 – 2x, then what is the acceleration at x = 2 m. For motion of an object along the x-axis the velocity v depends on the displacement x as v = 3x^2 - 2x then [...]

The deceleration experienced by a moving motor boat, after its engine is cut-off is given by dv/dt = -kv^3, where k is constant. If v0 is the magnitude of the velocity at cut-off, the magnitude after its engine is cut-off is given by dv/dt = -kv^3 The deceleration experienced by a moving motor boat the [...]
