A driver travelling at 100km/h Notices the speed limit changes to 50 km/h the driver takes your point 9 seconds to slow down to 50 km/h with constant acceleration we want to know how many metres a driver travels while slowing down

At very high pressures, gases become and will eventually a) more dense; become hotter b) more dense; change to a liquid or solid c) less dense; combust d) less dense; turn into a liquid

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy.work depends on the square of the change in potential energy.work is equal to the negative of the change in kinetic energy.work is equal to the square of the change in kinetic energy
