A car starts from rest and travels 5.0 s with a constant acceleration of -1.5m/s^2 for 3.6 s

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

Which of the following statements accurately describes the sign of the work done on the box by the force of the push? a. positive b. negative c. zero

Formulating a hypothesis: part i since the investigative question has two variables, you need to focus on each one separately. thinking only about the first part of the question, mass, what might be a hypothesis that would illustrate the relationship between mass and kinetic energy? use the format of " because when writing your hypothesis
