1. A person is pushing a 150 kg crate with an acceleration of 0.8 m/s2 up a 30-degree inclined plane with a friction coefficient of 0.3. What is the magnitude of the push? 2. A 20 kg crate is being lifted onto a platform by two people. The person on the left is lifting with 150 N at a 60-degree angle. The person on the right is lifting with 220 N at a 45-degree angle. What is the acceleration of the crate?

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.

Using the free-body diagram, calculate the net force acting on the sled. is the sled in a state of dynamic equilibrium?
