You’ve been spotted by an inmate. he’s asking you to trade. he won’t tell anyone you’re trying to escape if you give him one of your items. which item do you give him?

A1kg cart slams into a stationary 1kg cart at 2 m/s. the carts stick together and move forward at a speed of 1 m/sl. determine whether kinetic energy was conserved in the collision. use the law of conservation of energy to explain the collision

Ablock having mass m slides down an inclined plane. the force of friction between the block and the inclined plane is f, the block's weight is m g, and the normal force is n. (a) draw a free – body force diagram showing the forces acting on the block. (b) write down all relevant newton’s equations for a given situation.

Give one example to show that when substances are mixed,it may result in a chemical or a physical change depending on the conditions.
