During an automobile crash test, a 2000kg car is sent toward a cement wall at a speed of 14m/s and is brought to a stop in .5s. What was the average force of the car on the wall?

*30 points + brainliest answer* gravity is pulling an object into the sun. the closer the object gets to the sun, the greater the gravitational force that acts on the object, increasing its acceleration. a line graph plotting the speed of the object against time would have which shape? a: straight line of positive slope b: curved line that slopes upward c: curved line that slopes downward d: straight line of negative slope
