g A toy cannon uses a spring to project a 5.20-g soft rubber ball. The spring is originally compressed by 4.99 cm and has a force constant of 7.97 N/m. When the cannon is fired, the ball moves 15.4 cm through the horizontal barrel of the cannon, and the barrel exerts a constant friction force of 0.032 2 N on the ball. (a) With what speed does the projectile leave the barrel of the cannon

*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
