Question 1: A sphere of mass m = 2 kg, is released from rest at point A (see Figure 1.1). Due to gravity, the sphere goes down the path AB (which is an inclined plane, at 45 degrees from the horizontal line) and then hits the ground at point D; the vertical wall BC is 2000 cm high (see Figure 1.1 for details) Assume no friction. (a) Derive the velocity of the sphere when it reaches point B. (b) Derive the distance CD and the time the sphere takes to go from point B to point D. State and justify your assumptions and comment on your working. Marks will be assigned for the quality of the presentation of the working and of the comments. (You have to assign the value of L, in centimetres, by using the last 3 digits of your student ID, and then solve the question; for example, if your student ID is 19980169, then L=169 cm; if your ID is 17680039, then L=39 cm; if your ID is 14567000, then L=1000 cm).

An Earthball of mass 13.6 kg is rolling forward at 5.29 m/s when pushed by two students. A senior pushes the ball from behind, in the direction the ball is rolling, with a force of 207 N for 0.84 s, while a freshman pushes with a different force for a different amount of time, perhaps in a different direction. After the two pushes are completed, the Earthball is rolling forward at 9.85 m/s. What impulse did the freshman give to the Earthball? Include units in your answer.
I want the correct answer of that question please
2. A 20-g bullet is travelling at 400 m/s when it becomes embedded in a 3-kg stationary block. The coefficient of kinetic friction between the block and ground is 0.2 Use the principle of linear momentum and impulse to determine the velocity of system immediately after the bullet becomes embedded. Then, use the work-energy theorem to determine the distance that the block will slide before it stops. The frictional force between the block and surface can be neglected during the initial impact but cannot be neglected when analyzing the sliding distance of the block. #A
P.1) Three balls (A, B, and C) of equal mass m are projected toward each other in the horizontal plane such that they all impact simultaneously with the given velocities: vA = 10i m/s, vg = -5i m/s, and vc = (-11i – 9j) m/s. If the three balls stick together upon collision, what is the system's velocity just after impact? j VA VB -- |

▼ Part A Two blocks, each of mass m = 7.60 kg, are connected by a massless rope and start sliding down a slope of incline 0= 40.0° at t = 0.000 s. The slope's top portion is a rough surface whose coefficient of kinetic friction is μ = 0.350. At a distance d = 1.40 m from block A's initial position the slope becomes frictionless. (Figure 1)What is the velocity of the blocks when block A reaches this frictional transition point? Assume that the blocks' width is negligible.

A 1.5 kg mass is attached to a 1.6 m long rigid rod of negligible mass that is anchored to the ceiling. The mass is pulled back to an initial angle of 45°and released with an initial speed of 3.0 m/s. Note: The mass is initially moving down not up! 2. L m (a) [Hint: The height of the mass above its lowest point is L(1 – cos 0).] How fast is the mass moving at the bottoms of its swing, when 0 = 0°?
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.)
You place a 0.18-kg sonic ranger on a low-friction track in front of a 0.50-kg cart to measure the cart's velocity in the Earth reference frame, which turns out to be +(1.0 m/s). You are distracted, the cart hits the ranger in a totally inelastic collision, and the two objects then move forward together. A friend is running toward the cart with a velocity of -(3.5 m/s) with her sonic ranger on and pointed at the cart. ▾ Part A What is the x-component of the momentum of the cart with the ranger stuck to it, in your friend's reference frame?
