As shown below, a weeder is designed with a built in pivot point. The length of the handle r2 = 31 cm. The working end r1 = 6.2 cm. If a gardener using this weeder applied a 8.70 newton of force to pull the weed. Determine the resistive force the weed exerts on this tool.

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.
