Force is defined as mass times acceleration. Starting with SI base units, derive a unit for force. Using SI prefixes, suggest a convenient unit for the force resulting from a collision with a 10-ton trailer truck moving at 55 mi per hour and for the force resulting from the collision of a molecule of mass around \(10^{-20} \mathrm{kg}\) moving almost at the speed of light \(\left(3 \times 10^{8} \mathrm{m} / \mathrm{s}\right)\) with the wall of its container. (Assume a 1-second deceleration time for both collisions.)
