Two carts are rolling to the right along the same level track. Cart 1, with a mass m1 = 3.4 kg, is in the rear, rolling at a speed of 6.2 m/s and catching up to cart 2, which is rolling at a speed of 3.2 m/s. Choose signs carefully; only speeds are given. a) Cart 1 overtakes and collides with cart 2, sticking to it (both have Velcro pads). Afterward, they both continue rolling right, now at a speed...

Two carts, A and B, are connected by a rope 39 ft long that
passes over a pulley P (see the figure). The point
Q is on the floor h = 12 ft directly beneath
P and between the carts. Cart A is being pulled away from
Q at a speed of 3 ft/s. How fast is cart B moving toward
Q at the instant when cart A is 5 ft from Q?
Answer should be in ft/sec.

(Step 2.6) There were two questions concerning the forces acting on the carts connected by a string that you were to ponder: [a.] Which object, the string (between the carts) or cart A, exerts a force directly on cart B? Which object, the string or cart A, has a force acting directly on It from cart B? [b.] In light of your answers to the above question, do the forces measured in steps 2.1 through 2.4 (that is, the forces...

Two carts are riding on an air track as shown in the figure. At time t = 0 s, cart B is at the origin and traveling in the negative x direction with velocity v_B1. At that time, cart A is at the position shown and is at rest. Car B has twice the mass of cart A. The carts "bump" into each other but do not stick. Which physical parameter can be described by each of the following graphs?...

Problem 2 - A modified mass-spring-damper system: Model the modified mass-spring-damper system shown below. The mass of the handle is negligi- ble (only 1 FBD is necessary). Consider the displacement (t) to be the input to the system and the cart displacement az(t) to be the output. You may assume negligible drag. MwSpring-Damper System M0 Problem 3 Repeat problem 2, but with the following differences: • Assume the mass of the handle m, is not equal to zero. You may...

Guided Problem 7.4 An unequal match On a low-friction track, two carts coupled together are initially moving to the right at 2.0 m/s. The rear cart has an inertia of 2.0 kg, and the lead cart's inertia is one-third of that. An explosive charge attached to the coupling is ignited remotely, releasing 27 J of energy. One-third of that energy is dissipated to incoherent energy, such as noise, thermal energy, and damage to the carts. Use the Earth reference frame...

h 5. A cart rolls with negligible friction down a ramp that is inclined at an 8 = 32' above level ground. It is released from rest at a height h = 52 cm. What we want to do is to figure out how fast the cart will go when it reaches the bottom of the ramp. Let's begin by establishing the equations that model the motion of the cart. Recall that we are dealing here with an example of...

Two masses are connected by a cord that passes over a pulley
as shown in the figure. The pulley and cord have negligible mass
and m1 (2.0 kg) moves on a horizontal surface without friction, m2
(2.0 kg) is suspended vertically. What is the ACCELERATION of
m1?
