Suppose a 69-kg boy and a 42-kg girl use a massless rope in a tug-of-war on an icy, resistance-free surface. If the acceleration of the girl toward the boy is 3.0 m/s2, find the magnitude of the acceleration of the boy toward the girl.

A tangential force acts on the rim of a 2.0 kilogram disk-shaped wheel (0.50 m radius) and gives the wheel an angular acceleration of 4.8 rad/s^2. Neglect friction and find the magnitude of the force.

A 57 kg boy and a 42 kg girl use an elastic rope while engaged in a tug-of-war on a frictionless icy surface. If the acceleration of the girl toward the boy is 3.4 m/s2, determine the magnitude of the acceleration of the boy toward the girl. Answer in units of m/s2.

**PHYSICS**

Two crates , one with mass 4.00 kg and the other with 6.00 kg, sit on the frictionless surface of a frozen pond, connected by a light rope. Awoman wearing golf shoes(so she can get traction on the ice)pulls horizontally on the 6.00-kg crate with a force F that gives the crate ...
