If the velocity of a particle is nonzero, can the particle’s acceleration be zero? Explain.
Does the magnitude of your acceleration have to be greater than 9.8m/s² to leave the ground? explain.
3) A particle is moving along the surface of a vertical cylinder. The motion is described by the
relationships: r = A, 0 = 2nt and z = B sin(2nnt). In these equations A and B are constants
and n is an integer. What is the magnitude of the velocity of the particle at an arbitrary time t?
Take g = 9.81 m/s² when you need to use it.
