What is the difference between a derived SI unit and a funda-mental SI unit? Give an example of each

What type of quantity (for example, length, volume, density) do the following units indicate? (a) m3

What type of quantity (for example, length, volume, density) do the following units indicate? (g) Pa.

What type of quantity (for example, length, volume, density) do the following units indicate? (f) ms-1

"Give the derived SI units for each of the following quantities in base SI units: (g) energy = mass * 1velocity22"

Give the derived SI units for each of the following quantities in base SI units: (e) power = work/time

Give the derived SI units for each of the following quantities in base SI units: (a) acceleration = distance/time2

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 kgmoving almost at the speed of light (3 * 108 m>s) with the wall of its container. (Assume a 1-second deceleration time for both collisions.)
