When the cannon is fired, the ball moves 14.4 cm through the horizontal barrel of the cannon, and the barrel exerts a constant friction force of 0.031 9 N on the ball. (a) With what speed does the projectile leave the barrel of the cannon? m/s (b) At what point does the ball have maximum speed? cm (from its original position) (c) What is this maximum speed? m/s

A 6.00 ✕ 105 kg subway train is brought to a stop from a speed of 0.500 m/s in 0.400 m by a large spring bumper at the end of its track. What is the force constant k of the spring (in N/m)? (Enter a number.)
A block of mass 11.0 kg slides from rest down a frictionless 36.0° incline and is stopped by a strong spring with k = 2.30 ✕ 104 N/m. The block slides 3.00 m from the point of release to the point where it comes to rest against the spring. When the block comes to rest, how far has the spring been compressed?
A toy gun uses a spring to project a 6.2-g soft rubber sphere horizontally. The spring constant is 8.0 N/m, the barrel of the gun is 12 cm long, and a constant frictional force of 0.039 N exists between barrel and projectile. With what speed does the projectile leave the barrel if the spring was compressed 5.7 cm for this launch? (Assume the projectile is in contact with the barrel for the full 12 cm.)
A 0.100 kg block of ice is placed against a horizontal, compressed spring mounted on a horizontal tabletop that is 1.50 m above the floor. The spring has force constant 2000 N/m and is initially compressed 0.045 m. The mass of the spring is negligible. The spring is released, and the block slides along the table, goes off the edge, and travels to the floor. If there is negligible friction between the block of ice and the tabletop, what is the speed of the block of ice when it reaches the floor?

A 3.00 kgkg block on a horizontal floor is attached to a horizontal spring that is initially compressed 0.0360 mm. The spring has force constant 845 N/mN/m. The coefficient of kinetic friction between the floor and the block is 0.420. The block and spring are released from rest and the block slides along the floor. What is the speed of the block when it has moved a distance of 0.0170 mm from its initial position? (At this point the spring is compressed 0.0190 mm.) Express your answer with the appropriate units.

The block of mass 0.5 kg is pushed against a horizontal spring and the spring is compressed by x. After it is released it moves along frictionless horizontal surface and reaches the point A with a speed of v A = 11.0 m/s. The block experiences an average friction force of 6.0 N while sliding up the circular track. The radius of the track R=1.0 m. Can the block pass the top point (point B) without fall off of the track? R k mWWW No. It will fall off before reaching the top. No. The block will reach the top, but it will fall off the track. Yes. The block can safely turn the track. The block can only climb the quarter of the track. Can not determine with the given information Gönder Google Formlar üzerinden asla şifre göndermeyin. O O O O
