(i) State how a vector quantity differs from a scalar quantity.
(ii) State and explain whether momentum is a vector quantity or a scalar quantity.
A scientific probe of mass 45 kg45\text{ kg}45 kg is travelling in a straight line in deep space at a velocity of 1500 m/s1500\text{ m/s}1500 m/s. Assume no external forces act on the probe.
Calculate
(i) the momentum of the probe,
(ii) the kinetic energy of the probe.
An internal charge on the probe explodes, splitting it into two separate modules that continue along the same line of motion. One module speeds up while the other slows down.
(i) State what happens to the total momentum of the system.
(ii) Predict and explain what happens to the total kinetic energy of the system.
