Experts/ace/genius (and people that wanna actually ) which force is needed to give a 4.5 - kg bowling ball an acceleration of 9 m/s^2? a. 0.5 n b. 2 n c. 40.5 n d. 36.5 n

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?
