Question

A car is travelling along a straight road with speed v measured in m/s. The power P measured in watts required to overcome external forces opposing the motion is given by the p=CV+KV³, where c and k are constants. use base units to obtain SI unit for constant K​

Answer 1

Answer:

K = kg/m

Explanation:

as velocity has units of m/s  V³ has units of m³/s³

power has units of J/s = N•m/s = kg•m/s²•m/s = kg•m²/s³

kg•m²/s³ = K(m³/s³)

K = kg•m²/s³•s³/m³

K = kg/m
