Please answer this NEATLY, COMPLETELY, and CORRECTLY for an UPVOTE. The wooden block (mass m = 0.5358 kg) is released from rest at A by a compressed spring (compressed length 0.6 m, undeformed length 1 m, spring constant k = 150 N/m). The block is allowed to slide through the rough horizontal surface (A to B), then along the smooth circular ramp (B to C, central angle θ = 47.2°, until the block is released after point C. Calculate the speed of the block at points B and C. Also, what is the magnitude of the normal force exerted to the block just before the block leaves the ramp? Neglect the geometry of the block. NOTE: Use Work-Energy Method to solve for the speeds; use Force-Mass-Acceleration (FMA) Method to compute for the normal force.
Hello, can you help me answer this question with complete solution and illustration. *A Land Cruiser having a mass of 1500 kg goes through an intersection and i stravelling from north to south when it is hit by a Mitsubishi Pajero of mass 220 kg travelling from east to west. The two cars slid as one due to impact and stops 5.39 m west and 6.43 m south measured from impact point. It is known that the coefficient of kinetic friction between the cars and the road is 0.75. How fast each of the car is travelling before collision?
Forming a shock absorber, two springs of equal length are nested together. If the maximum compression of the springs is 0.25 and the outer spring has a stiffness of Ka = 420 N/m, what stiffness is required of the inner spring Kb? The design of the spring system is such that if a mass of 2.5 kg is at rest, then dropped from a distance of 0.75 m above the springs, the spring system will catch and stop the mass.
Q2: An automobile with mass of 700 Kg goes around a 500 m-radius curve at a constant speed of SO Km/h. if the road is not banked, what frictional force must the road exert on the ties so that they will ‘maintain motion along the curve?
A lightweight drone (1.00 kg) is launched at 800 m high and moves upward at a constant velocity (whileignoring the effects of gravity only on the drone). The balloon, when measured at a horizontal distance fromyou, is about 1600 m away from you. At the moment when the drone moves, you shoot a bullet (weight =180g) with an initial velocity of 1009 m/s at a fixed angle α, where sin α=3/5 and cos α= 4/5. (g = 9.8 m/s2) d. Provided that the collision is inelastic, calculate the speed after the collision.e. Calculate the height the two objects taken from the impact up to the maximum height before it startsfalling to the ground.
A block weighing 2.50 kg begins its motion from a stationary position at point A, located at the highest point of a frictionless ramp. The ramp is inclined at an angle of 40° relative to the horizontal and has a length of 1.50 m. As the block slides down the ramp, it reaches a region between point B and point C, which is a rough horizontal surface with a kinetic friction coefficient of 0.30. After covering a distance of 1.00 m on the horizontal surface, the block encounters a lightweight spring with a spring constant of 900 N/m. A. Find the total energy for point A and point B? B. Find the speed of the block at point B? C. What is the cumulative work performed on the block as it moves along the rough horizontal surface? D. By employing the work-energy theorem, determine the velocity of the block at point C just before it collides with the spring?
Read the question carefully and give me right solution A slender rod with a length of 40 cm and a mass of 2 kg is falling at a rate of 1.5 m/s and at a 35-degree angle as shown below. The rod then strikes a surface and rebounds off it. Assuming that the coefficient of restitution for the impact is .9, and that there is negligible friction between the body and the surface,what is the expected velocity of the center of the rod (C) and the angular velocity immediately after impact?
The figure depicts two pucks on a frictionless table. Puck 2 is four times as massive as puck 1. Starting from rest, the pucks are pushed by two equal forces. 1-Which pucks will have the grater kinetic energy upon reaching the finish line? 2- Which puck will reach the finish time first ?
In a 300-rough incline, a 1.25 kg block is initially at rest beside a spring that is compressed by 24 cm as shown in the figure below. The spring has a spring constant of 180 N/m and the coefficient of sliding friction between the incline and the block is 0.23. When the spring is released, (a) how far up the incline (with respect to its initial position) will the block slide before sliding back? (b) What is the speed of the block at the instant it is 0.34 m from its initial position?
The figure shows a junction of mass m = 10kg sliding on a rod in a vertical plane. Positioned 1 simpai is stationary and horizontal spring and tensioned Fp = 300N. If the spring constant is k = 1kN/m and the average frictional force between the rod and the junction is F = 30N. Calculate the speed at position 2. (Ans: 3.47m/s)
A block of mass m= 2.0 kg is released from rest on an inclined plane at a height of h = 1.5 m. It moves down the rough incline with slope theta= 30.0°and continues on the horizontal frictionless surface. As shown in the figure, there is a spring with negligible mass and force constant k = 300 N/m. The coefficient of kinetic friction between the block and the incline is 0.250 What is the speed of the block when it gets down on the horizontal surface before it touches the spring? The box continues to move on the horizontal surface and compresses the spring. What will be the maximum compression of the spring?
