What acceleration is needed to accelerate a car from 36km/h to 72km/h in 25 seconds

Two objects of different mass start from rest, are pulled by the same magnitude net force, and are moved through the same distance. the work done on object 1 is 900 j. after the force has pulled each object, object 1 moves twice as fast as object 2. how much work is done on object 2?

How does an observation about an object differ from an inference about that object

What are the similarities & differences between a thermistor and a light dependent resistor in physics?
