A car is traveling at 15.5 m/s, and the driver sees a traffic light turn red. After 0.321 s (the reaction time), the driver applies the brakes, and the car decelerates at 6.2 m/s2. What is the stopping distance of the car, as measured from the point where the driver first sees the red light?

How does the amount of energy required to hold each proton and neutron in the nucleus compare to the energy released when they are removed?

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?
