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...

A 5.0-kg carl (cart 1) rolling cast on a level, frictionless track at 18.0 m/s, collides with a stationary 4.0-kg cart (cart 2). After the collision, cart 1 is still rolling cast, but now at a speed of 2.0 m/s. (a) Assuming the total momentum of the two-cart system is conserved, calculate the final velocity of the second cart. (b) Before the collision, the system's total kinetic energy was 810 J. Calculate the total kinetic energy of the two-cart system...

Cart on an Incline plane. Start up the Dynamics Track apparatus. Set the µKS? # stepper to zero (µk = 0.12 and µs = 0.18 by default). Please notice that the dynamic track has a feature to be tilted by dragging when the mouse cursor is in the colored part of either end of the track. The message box informs that the track can be tilted up or down. With the brake off, turn on the friction pad and put...

Suppose that while a mining cart is rolling along a straight, frictionless, horizontal track with some initial speed, it starts to rain. If the rain falls vertically into the cart and begins to accumulate within it, flooding the cart, determine the following 19. is the momentum of the system conserved in the horizontal direction? a. Yes b. No 20. Is the momentum of the system conserved in the vertical direction? a. Yes b. No 22.If a 1200 kg train car...
A bicycle slows down uniformly from an initial velocity vi = 8.70 m/s to rest over a distance of 125 m.
1. A bicycle slows down uniformly from an initial velocity vi = 8.70 m/s to rest over a distance of 125 m. Each wheel has an overall diameter of 690 cm. You can assume that the wheels roll without slipping. (a) Calculate the angular speed of the wheels at the initial instant (t = 0). (b) Calculate the total number of revolutions each wheel rotates before coming to rest. (c) Calculate the angular acceleration of the wheel (d) Calculate the time it takes to...

To find the acceleration of a glider moving down a sloping air track, you measure its velocity at two points (?1 and ?2); and the time t it takes between them: v1 = .21 ± 0.05 m/s v2 = .85 ± 0.05 m/s 2 = 0 t = 8.0 ± 0.1 s a. Assuming all uncertainties are independent and random, and acceleration is calculated using a = (v2-v1)/t, what should you report for a and its uncertainty? b. You calculate...
