The height covered by the projectile above the point B.

Question

A spring project uses a plastic ball. (a) With what speed does the projectile leave the barrel of the cannon? (b) At what point does the ball have maximum speed? (c) What is this maximum speed? When the ball is 5.30 grams. The spring is originally compressed by 5.00 cm and has a force constant of 8.00 N/m. When the ball is fired and moves 15.0cm through the horizontal barrel of the cannon and the barrel exerts a constant friction force of 0.0320N on the ball.

In a needle biopsy, a narrow strip of tissue is extracted from a patient with a hollow needle. Rather than being pushed by hand, to ensure a clean cut the needle can be fired into the patient's body by a spring. Assume the needle has mass 5.60 g, the light spring has force constant 440 N/m, and the spring is originally compressed 8.10 cm to project the needle horizontally without friction. (The spring is fully uncompressed before the needle contacts the skin.) The tip of the needle then moves through 2.40 cm of skin and soft tissue, which exerts a resistive force of 7.50 N on it. Next, the needle cuts 3.50 cm into an organ, which exerts a backward force of 9.70 N on it. (a) Find the maximum speed of the needle. m/s(b) Find the speed at which a flange on the back end of the needle runs into a stop, set to limit the penetration to 5.90 cm. m/s

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
