A model train set includes two cars that are coupled to- gether. The front car has mass m₁ = 2.5 kg whereas the rear car has mass m₂ 2.2 kg. The two cars are travel- ing with speed v₁ = 3.0 m/s along a track with negligible friction. Suddenly, the two cars become uncoupled, and a compressed spring that was lodged between them pushes the cars apart. (The spring remains attached to the rear car afterward, and its mass has already been included in the m₂ value given earlier.) The front car's speed v₁ is now twice as large as the rear car's speed v2. What is the speed v₁ of the front car? For the representation, be sure to in- clude a before/after diagram of the cars with their velocity vectors properly labeled. =

A 10 kg block A rests on a smooth surface and the spring is compressed 0.1 m. It is attached to an inextensible cord over frictionless, weightless pulleys with a mass B of 24 kg, as shown.

A constant force of ''F'' acts on a mass as shown. The mass starts its motion from rest at position 1, the unstretched length of the spring is 250 mm, and the spring modulus is k=1,5 k?/m.

Principle of Angular Impulse and Momentum To apply the principle of angular impulse and momentum to find final speed and the time to reach a given speed. As shown, ball B, having a mass of 10.0 kg, is attached to the end of a rod whose mass can be neglected.

Gayle runs at a speed of 4.10 m/s and dives on a sled, initially at rest on the top of a frictionless snow-covered hill. After she has descended a vertical distance of 5.00 m, her brother, who is initially at rest, hops on her back and together they continue down the hill. What is their speed at the bottom of the hill if the total vertical drop is 15.0 m? Gayle's mass is 46.5 kg, the sled has a mass of 5.25 kg and her brother has a mass of 30.0 kg.

The amusement park ride consists of a 200-kg car and passenger that are traveling at 4.6 m/s along a circular path having a radius of 8 m. At t = 0, the cable OA is pulled in toward O at 0.5 m/s.

To apply Newton’s second law and the theorem of conservation of energy to solve kinetic problems. A bungee jumper wants to jump off the edge of a bridge that spans a river below. The jumper has a mass m, and the surface of the bridge is a height h above the water. The bungee cord, which has lengthL when unstretched, will first straighten and then stretch as the jumper falls.Assume the following: The bungee cord behaves as an ideal spring once it begins to stretch and has spring constant k. The jumper does not actually jump but simply steps off the edge of the bridge and falls straight downward. The jumper's height is negligible compared to the length of the bungee cord. Thus, the jumper can be treated as a point particle. Use g for the magnitude of the acceleration due to gravity. How far below the bridge, d, will the jumper eventually be hanging, once the jumper stops oscillating and comes finally to rest? Assume that the jumper does not touch the water. Express your answer in…
The 18 000-kg F-35B uses thrust vectoring to allow it to take off vertically. In one maneuver, the pilot reaches the top of her static hover at 200 m. The combined thrust and lift force on the airplane applied at the end of the static hover can be expressed as F = (44t + 2500t2)i + (250t2 + t + 176 580)j, where F and t are expressed in newtons and seconds, respectively. Determine how long it will take the airplane to reach a cruising speed of 1000 km/hr (cruising speed is defined to be in the x-direction only).
