There is a compressed spring between two laboratory carts of masses m1 and m2. Initially, the carts are held at rest on a horizontal track (Fig. P10.40A). The carts are released, and the cart of mass m1 has velocity v1 in the positive x direction (Fig. P10.40B). Assume rolling friction is negligible. a. What is the net external force on the two-cart spring system? b. Find an expression for the velocity of cart 2. c. Sometimes, mistakes are made in a laboratory. For example, what changes in parts (a) and (b) if the track is not level as shown in Figure P10.40C? Explain your answer.

In an ideal experiment, an elastic ball is let go from a certain height, then the ball hits the ground and bounces back to the same height it was released; then the motion repeats, each time the ball bounces back to the initial height. From what height was the ball released if 1.35s lapse between consecutive bounces? Consider g = 9.80 m/s2. How would I go about solving this problem?
You wake up one morning to find yourself in a strange room with opaque walls, and no visible doors or windows. You decide to do some experiments to find out more about your strange situation. Your own body mass is 54.7 kg. You pick up an object and drop it from rest, starting at a height of 1.20 meters above the floor, and it hits the floor 0.396 seconds later. You can ignore air resistance. Based on the outcome of this experiment, when you step on the scale provided for you, what weight will it register for your body?
Two masses are initially at rest (m₁ = 56 g and m₂ = 74 g) and are both in contact with compressed springs (as shown in the figure). The springs have spring constants k₁ = 2100 N/m and K₂ = 1800 N/m. Spring 1 has an initial compression of 2.4 cm and spring 2 has an initial compression distance of 2.1 cm. Both masses are released at the same time and move toward each other along a frictionless surface. What are the velocities of the two masses once they lose contact with the springs? Let motion to the right be positive and to the left be negative. Give your answers in m/s, including a minus sign where needed: V1 V2 Uf The collision of the two masses is completely inelastic (meaning they stick together). What is the final velocity (after the collision) of the combined masses? Be sure to include a minus sign if the motion is to the left: m₁ m/s Question 1 m/s m₂
In the figure, block number 1 has a mass of 2 kg and block number 2 has a mass of 5 kg. The surface is frictionless and the spring constant k = 1120 N / m ‘. Objects move to the right at the speeds given in the figure. When the collision occurs after a while, the compression in the spring becomes maximum when the blocks have the same speed. What is the maximum compression of the spring?
The massless spring of a spring gun has a force constant k = 0.04 N/cm. When the gun is aimed vertically, a 40 g projectile is shot to a height of 5.0 m above the end of the expanded spring. (See below.) How much was the spring compressed initially? (Find d, in meters.)
