An infant's toy has a 120 g wooden animal hanging from a spring. If pulled down gently, the animal oscillates up and down with a period of 0.44 s . His older sister pulls the spring a bit more than intended. She pulls the animal 26 cm below its equilibrium position, then lets go. The animal flies upward and detaches from the spring right at the animal's equilibrium position.If the animal does not hit anything on the way up, how far above its equilibrium position will it go?

1. Assume that hanging a 100 gram mass from a given spring stretches the spring by 2 cm. If two springs of this kind are connected back to back (series configuration), how much would the combination stretch if a 200 gram mass is suspended? a. 1 cm b. 2 cm c. 3 cm d. 4 cm e. none of these 2. What would be the answer to the previous question if the two springs were connected in parallel configuration? a....

A toy car with a mass of 120 g moves to the right with a speed of 0.64 m/s. A small child drops a 36.0-g piece of clay onto the car. The clay sticks to the car and the car continues to the right. What is the change in speed of the car? Consider the frictional force between the car and the ground to be negligible.

A toy cannon uses a spring to project a 5.20-g soft rubber ball. The spring is originally compressed by 5.03 cm and has a force constant of 8.08 N/m. When the cannon is fired, the ball moves 15.6 cm through the horizontal barrel of the cannon, and the barrel exerts a constant friction force of 0.032 1 N on the ball. (a) With what speed does the projectile leave the barrel of the cannon? (b) At what point does the...

A toy cannon uses a spring to project a 5.38-g soft rubber ball. The spring is originally compressed by 4.91 cm and has a force constant of 8.08 N/m. When the cannon is fired, the ball moves 15.6 cm through the horizontal barrel of the cannon, and the barrel exerts a constant friction force of 0.032 6 N on the ball. (a) With what speed does the projectile leave the barrel of the cannon? m/s (b) At what point does...

A toy cannon uses a spring to project a 5.39-g soft rubber ball. The spring is originally compressed by 5.04 cm and has a force constant of 8.10 N/m. When the cannon is fired, the ball moves 15.6 cm through the horizontal barrel of the cannon, and the barrel exerts a constant friction force of 0.032 5 N on the ball. (a) With what speed does the projectile leave the barrel of the cannon? m/s (b) At what point does...

An ideal spring is in equilibrium, hanging from a ceiling with a 1 kg mass at...

An ideal spring is in equilibrium, hanging from a ceiling with a 1 kg mass at the end. At rest, the length of the hanging spring is 10 cm. Then, an additional 5 kg block is added to the spring, causing its length at rest to increase to 13 cm. The 5 kg block is then removed. Starting from rest, when the 5 kg block is removed, the spring begins to oscillate. What will the spring’s velocity be, the third...

A spring is hanging motionless from the ceiling of a room on the earth. You attach a mass to the end of the spring and after releasing the mass, you observe that the spring extends a distance before momentarily coming to a halt. What then must be the distance below just the spring's equilibrium position to the new equilibrium position of the spring-mass system? A. B. C. D. A spring is hanging downward from the ceiling of a room on the...

A mass weighing 8 lb is attached to a spring hanging from the ceiling, and comes to rest at its equilibrium position. The spring constant is 4 lb/ft and there is no damping. A. How far (in feet) does the mass stretch the spring from its natural length? L= B. What is the resonance frequency for the system? ω0= C. At time t=0 seconds, an external force F(t)=3cos(ω0t) is applied to the system (where ω0 is the resonance frequency from...
