a ball starint from rest accelerates uniformly at 5.0 meters per second 2 as it rolls 40. meters down an incline. How much time is required for the ball to roll the 40. meters

How can you increase the strength of an electromagnet?

The great sandini is a 60.0-kg circus performer who is shot from a cannon (actually a spring gun). you don’t find many men of his caliber, so you him design a new gun. this new gun has a very large spring with a very small mass and a force constant of 1100 n/m that he will compress with a force of 4400 n. the inside of the gun barrel is coated with teflon, so the average friction force will be only 40.0 n during the 4.00 m he moves in the barrel. at what speed will he emerge from the end of the barrel, 2.50 m above his initial rest position?

The applied force of 3 washers will increase the applied force on the car to n.
