A horse is used to help stack hay in a barn. At the instantshown, the length of rope, r, is 7 m, the angle the ropemakes with the horizontal is = 50°. The 750-kg horseis walking at a velocity of 1.5 m/s and is speeding up ata rate of 0.25 m/s². The mass of the bale is 60 kg.Determine at this instant,(a) the speed of the bale,(b) the tension in the rope(c) the average force between the ground andthe horse's feet.

Given data as per the question Length of rope =7 m Mass of horse =750 kg velocity =1.5 m/s Mass of…

A motorcycle and rider have a combined mass of 350kg. The vehicle's velocity is 100 km/hr. The rider is to go up a hill incline of 10 meters. The wheels each have a mass of 20 kg and a diameter of 500mm. The wheel design consists of 6 spokes with a mass of 0.5 kg for each spoke. a. Determine the vehicle's velocity at the top of the hill, assuming it was a rolling vehicle with engine being turned off. a. Indicate the vehicle's velocity at each meter through the climb. b. Explain the transfer energy and how this affects the behaviour of the system. At another point in its journey, the motorcycle and rider travel at 80 km/h around a left-hand bend of radius 30m. Calculate: a) The angular velocity of each wheel. b) The moment of inertia of each wheel. c) The angular momentum of the wheel prior to entering the bend. d) The magnitude of the gyroscopic torque produced on the bike as the rider is driving around the bend. What is the effect and why is it important to calculate the gyroscopic…
Q6. As shown in the image below, the spring (with spring constant k = 2.4 kN/m) is fixed to block A, and block B is pressed against the spring. The masses of blocks A and B are mÃ = 19 kg and m² = 15 kg, respectively. The spring is initially compressed by 240 mm, and then both blocks are released from rest. Determine the velocity of block A at the instant block B loses contact with the spring. Right is considered the positive direction and negative sign must be included if the velocity points to the left. (Hint, neglect friction, and since there is no impulsive force, energy is conserved.) Please pay attention: the numbers may change since they are randomized. Your answer must include 3 places after the decimal point, and proper SI unit. Your Answer: Answer A www k units B
Q3. As shown in the image below, the freight cars A and B are approaching each other, and they have a mass of mA = 18 Mg and mg = 13 Mg, respectively. The må directions of their initial velocities are shown in the image, and the speeds are VÃ,1 = 3.9 m/s and VB,1 = 2.7 m/s. After collision the cars rebound, such that B moves to the right with a speed of 1.7 m/s. If A and B are in contact for 0.4 s, find the average impulsive force (in kN) which acts between them. Please pay attention: the numbers may change since they are randomized. Your answer must include 1 place after the decimal point. A Your Answer: VA,1 Answer B KAM VB.1
