If x is measured in meters (m), t is measured in seconds (s), and u is measured in meters per second (m.s-1), what are the units of the constants c1 and c2 in the equation knowing that units must balance on both sides of the equation. u2 = c1 u2 + 2 c2 x ?
C1has no unit and C2 has the unit m2.s-2
C1 has the unit m.s-1 and C2 has the unit m
C1 has the unit m and C2 has the unit m.s-1
C1 has no unit and C2 has the unit m.s-2
