1.15. 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 an S. I. unit for
constant k.

A3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular? a 3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular?
