Neil and Gus are having a competition to see who can launch a marble highest in the air using a spring. Neil has a firmspring with a spring constant of 46.8 N/m and a maximum compression of 11.0 cm. Gus's spring is less firm than Neil'swith a spring constant of 11.7 N/m, but its maximum compression is greater at 21.0 cm. The mass of the marble is 4.5 g.Ignore the effects of air resistance. What is the speed vc of Gus's marble as it leaves his spring? Vg =What is the speed Un of Neil's marble as it leaves his spring? Vn=

A large toy car is pushed horizontally by a spring, and the spring has a spring constant of 135 N/m. What is the mass of the toy car if compressing the spring 0.055 m (before the toy starts moving) causes it to reach a speed of 0.75 m/s? (Note - the height of the toy does not change.) What equation will be best for calculating this value? Your answer: O mgh, = O mgh, =mv? %3D 0 글씨로=mghy
A toy cannon uses a spring to project a 5.33-g soft rubber ball. The spring is originally compressed by 4.99 cm and has a force constant of 8.08 N/m. When the cannon is fired, the ball moves 15.3 cm through the horizontal barrel of the cannon, and the barrel exerts a constant friction force of 0.031 O N on the ball. (a) With what speed does the projectile leave the barrel of the cannon? m/s () At what point does the ball have maximum speed? cm (from its original position) (c) What is this maximum speed? m/s
A 5 kg block is attached to a spring of constant k = 2400 N/m. The coefficient of friction between the block and the ground is 0.4. Under its initial condition, a force F is applied to the block until the restoring force of the spring reaches 100 N. To reach its final condition, the applied force F is removed. Then, the block moves and the spring returns to its unstretched position. Use 9.81m/s^2 for the gravity. a) Using the formula Fspring=kx, determine the distance in meters of the block from its unstretched position until it has a restoring force of 100N. b)Determine the work done by friction in Joules from the initial position (stretched) to its final position (unstretched). c)If the total work done on the system is 1.2658 J, determine the final velocity of the block (by relating work and kinetic energy)
