Atoy cannon uses a spring to project a 5.31 g soft rubber ball. the spring is originally compressed by 5.09 cm and has a force constant of 7.99 n/m. when the cannon is fired, the ball moves 15.2 cm through the horizontal barrel of the cannon, and there is a constant frictional force of 0.0325 n between the barrel and the ball. (a) with what speed does the projectile leave the barrel of the cannon

A3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular? a 3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular?
