2 pts A toy manufacturer wishes to design a pogo stick so that when a child...
A pogo stick has a spring with a force constant of 2.50 × 104 N/m , which can be compressed 12 cm. To what maximum height, in meters above the compressed position of the spring, can a child jump with the stick using only the maximum elastic potential energy in the spring, if the child and stick have a combined mass of 35 kg?
A 25 kg child bounces on a pogo stick. The pogo stick has a spring with spring constant 2.0x10^4 N/m. When the child makes a nice big bounce, he finds that at the bottom of the bounce he is accelerating upwards at 9.8 m/s^2. How much is the spring compressed?
2. A toy car has a mass of 0.400 kg. It gets thrown at 9.0 m/s toward a spring-held block with a mass of 1.1 kg. As a result of the impact, the car bounces backward from the block. It does not stick. The block compresses the spring by a maximum distance of 24 cm. After it bounces, the car is traveling 1/3 as fast as it was before it hit the block. It does not stick What is the...
A spring-loaded toy gun is used to shoot a ball of mass m=1.50 kg straight up in the air, as shown in (Figur 1) . The spring has spring constant k =667 N/m. If the spring is compressed distance of 25.0 centimeters from its equilbriurn position y = 0 and then released, the ball reaches a maximum height hax (measured from the equilibrium position of the spring). There is no air resistance, and the ball never touches the inside of...
Two children are trying to shoot a marble of mass m into a small box using a spring-loaded gun that is fixed on a table and shoots horizontally from the edge of the table. (Figure 1)The edge of the table is a height H above the top of the box (the height of which is negligibly small), and the center of the box is a distance d from the edge of the table. The spring has a spring constant k....
Question 18 2 pts Assume when using a meter stick measuring can be done so that the last significant figure is in the tenth of a millimeter digit. If you are measuring an object with length between 6 and 7 cm, how many significant figures will result if you only use the part of the meter stick between the 1-cm and 9 cm positions? 2 03 4 5 more than 5

2m 20 1m You have built an enormous spring-loaded Hot Wheels track that will propel a 50 gram toy car through a loop and launch it across the room. The spring constant is 800 N/m, the spring launcher has an initial spring displacement of 5 cm. What is the maximum radius R of the loop such that the car moves around the loop without falling off at the top, so that the toy car can make to the end point...
Question 2 10 pts A block of mass m = 4.0 kg is dropped from height h = 74 cm onto a spring of spring constant k = 1530 N/m (See the figure below). Find the maximum distance the spring is compressed. (Your result must be in meters and include 2 digit after the decimal point. Maximum of 5% of error is accepted in your answer. Take g = 9.8 m/s 2.) pecccccee

4. In this problem, we design a shock absorber of a vehicle. A as modeled in the figure below. The road surface is a sinusoidal shape with the wave length car is moving on a rough road m and the amplitude 5 cm. The mass of the vehicle is 2000 kg and the spring constant is 100 kN/m. 2000kg 100 kN/m 5 cm 3 m Figure 1: Assume that the size of the tire...
