1. In the pulley arrangement shown, a Hispaniolan Solenodon of mass 1.0 kg (an ANIMAL considered a living fossil and one of the few known venomous mammals) is riding a cart of mass is 3.0 kg. The hanging object mass, m, is unknown. The coefficient of friction between the cart and the table is 0.15 and the rope is connected to the cart. The animal will not slide off the cart (i.e, you can consider it to be stuck to the cart as though it were one object). If the acceleration of the mass and cart is 4.0 m/s Find the force of friction on the cart (a) (b) (c) Solve for the hanging object's mass 'm' Find the magnitude of tension in the string

Torque

Torque is the rotational equivalent of linear force in physics and mechanics. Based on the course of study, it is also known as the moment of force, rotational force, or turning effect.
