Q4. As shown in the image below, the freight cars A and B are approaching each other, and they have a mass of mA = 23 Mg and mB = 15 Mg, respectively. The directions of their initial velocities are shown in the image, and the speeds are VÃ,1 · 2.5 m/s and VB,1 = 2.1 m/s. If the two cars collide and get stuck together, then move with the same velocity, determine their common velocity after the collision. Right is considered the positive direction and negative sign must be included if they move to the left after the collision. Please pay attention: the numbers may change since they are randomized. Your answer must include 3 places after the decimal point, and proper Sl unit. A Your Answer: VA,1 Answer units B VB.1

A car A is stuck on the railroad tracks as a train B approaches with a speed of 120 km/hr. As soon as the problem is detected, the train's emergency brakes are activated, locking the wheels and causing the train's wheels to slide relative to the tracks. If the co-efficient of kinetic friction between the wheels and the track is 0.2, use work energy principle to determine the minimum distance d at which the brakes must be applied to avoid a collision under the following circumstances. Mass of the train is 195,000 kg. A B d
Body U with mass 5m is stacked on the top body W with mass m, and released. The bodies are in contact along the frictionless interface at 45° to the vertical. The body U is in contact with the frictionless vertical wall. Body W lies on the floor with coefficient of friction u. Relevant dimensions are shown in the figure. Express the results in terms of given quantities: m, g, h and µ (except when µ is given numerically). You need not evaluate sin 45° = cos 45° = 2/2. h U: 5m C 45 D W: m 3h
: A pilot in a fast jet aircraft loops the loop. The radius of the loop is 400 m, and the aircraft has a speed of 150 m/s when it passes through the bottom of the loop. What is the apparent weight that the pilot feels; in other words, what is the force with which she presses against her chair? Express the answer as a multiple of her normal weight
3) The ME Department just purchased a new mega-drone that weighs 220 lbs and can descend autonomously to land on its own. The drone company included the graph shown below for how much force is applied to the Thrust 'T'. If the operator allows the autonomous descent when the drone has an initial downward velocity of 2 ft/s, calculate the velocity of the drone after 3 seconds.

A loaded truck collides with a car causing a large amount of damage to the car. Which of the following is true about the collision? During the collision, the truck has a greater displacement than the car. The force on the truck is greater than the force on the car. During the collision, the truck has a greater acceleration than the car. The force on the truck is the same in magnitude as the force on the car.
Problem 2: A rocket is launched from the ground, straight up, from rest. The expelling gases from the bottom of the rocket provide it with a constant upward acceleration a. After 20 sec, the rocket reaches a height of 6500 m. At this point, the rocket depletes its fuel supply and the engines of the rocket are no longer working. At this point, the rocket goes into free fall, with an acceleration of –9.8 m/sec2. The left part of the figure below applies to parts (a)-(b). (a) What is the rocket's initial upward acceleration a? (b) What is the rocket's speed v, 20 sec after take-off? Hint: The answer is v = 650 m/sec. For parts (c)-(d), the rocket engines are now off. We will redefine the time to t = 0. The final properties for when the engines were on make the initial properties for when the engines are off: y0 = 6500 m, vo = 650 m/sec, and the acceleration is now a = -g, with g = 9.8 m/sec?. The right part of the figure below applies to parts (c)-(d). (c) What is ymaz, the largest height…
A 754g ball starts from rest and slides down a frictionless, elevated ramp. When it leaves the bottom of the ramp, it is moving perfectly horizontally, 1.83m above the ground, and hits the ground 0.92m away from the ramp. a. At what height above the ground did the ball start? b. How fast was the ball moving when it left the ramp? c. How fast was the ball moving when it hit the ground?
Situation 02. A private jet carrying Peter Parker takes off with a constant acceleration of 5 m/s?. Natasha Romanoff jumps on just as the jet plane lifts of the ground. They took a fight 10 seconds on the jet then suddenly the Romanoff shuts the engine off and jumps out of the jet. The instant the engine shut down, the jet is assumed in free fall. Romanoff deploys a jet pack 7s after leaving the helicopter with a constant downward acceleration of 2 How far is Romanoff above the ground when the jet crashes into the ground?
4. A plane cruising at an altitude of 500 m from the ground and 22 degrees from the horizontal at a speed of 180km/hr releases a package. Calculate the distance with which the package will drop from its original position and compute the time before it hits the ground.
2. A block travels past point A with a speed of 8 m/s along a smooth surface until it reaches a rough surface of length L=20 m and a coefficient of kinetic friction of 0.8. If the height h₁ = 8 m, and h₂ = 3 m. Determine (A) the speed of the block at point B (B) whether the speed at point C (C) reaches point D. If so, what is the speed at point D, if not, how far is the rough surface that cross the beam?
