- The vehicle shown starts from rest at the bottom of the hill and accelerates up the hill due to the force FR from the road. Note that this is a static friction force and is not dissipative. Vrop = 9.7 m/s m = 1600 kg h = 50 m FR = 7300 N 0 = 25° A) If the vehicle reaches the top of the hill with the speed shown, how much thermal energy is dissipated in the process? B) Assuming that air drag, Fang , is the only dissipative force during this process, try to estimate the cross-sectional area of the vehicle "seen" by the air. In the formula for air drag, regard the car's speed as being a constant v = 5.0 m/s (this speed is roughly half of the starting and ending speeds). Use C = 0.5 for the drag coefficient and p = 1.25 kg/m³ for air density.arrow_forwardQ 3arrow_forwardPlease include the figure, fbd and formula. An empty freight car with a mass of 10,000 kg rolls at 5 m/s along a level track and collides with a loaded car with a mass of 20,000 kg, standing at rest with brakes released. Friction can be neglected. If the cars couple together, find their speed after the collision. a. Find the decrease in kinetic energy as a result of the collision. b. With what speed should the loaded car be rolling towards the empty car for both to be brought to rest by the collision?arrow_forward
- Suppose that you are designing a system to prevent the contents of packages from being damaged when they slide off of a conveyor line. Your solution is to have a linear spring that compresses 6 inches when a package weighing 80 pounds impacts the system at a speed of 10 feet per second. What value of k, the spring constant, should you specify? Assume that the spring is at its free length before the package makes contact, and that friction can be neglected. (Hint: remember to use consistent units!) 10 ft/s www. Problem 4: What is the maximum acceleration in g's that the package in the previous problem will experience? (Use equations of motion for this problem.)arrow_forwardA crate of 67 kg simply stands on the moving cart with constant acceleration a. The height from the center of gravity to the cart, L, is 1.2 m, and the angle = 12°. What is the maximum acceleration a (in m/s²) the cart can have without tipping over on the cart? The coefficient of static friction between the crate and the cart is μg = 0.55. Please pay attention: the numbers may change since they are randomized.
