A 50 N force is applied at the end of a 30 cm wrench.  If the force makes an angle of 67o with the wrench, what is the magnitude of the torque about the point of rotation?

Determine a unit vector that is perpendicular to both 

Paul pulls on a rope attached to his sleigh with a force of 60 N.  If the rope makes an angle of 15o with the horizontal, determine the force that pulls the sleigh forward.

An airplane is travelling due north at an airspeed of 250 km/h when it encounters a wind from the west. The resultant ground speed is in a direction N20oE.  What is the rate at which the wind blows?

A 50 N force is applied at the end of a 30 cm wrench.  If the force makes an angle of 67o with the wrench, what is the magnitude of the torque about the point of rotation?

Calculate the amount of work done when a sleigh is pulled 50 m by a force of 30 N applied at an angle of 30o with the ground.

Explain why three forces of magnitudes 4 N, 5N, and 10 N cannot produce equilibrium.
