Two different air track carts are sliding to the right at 1.0 m/s. The leading cart has a mass of 500g and the trailing cart has a mass of 200g. They are being held together by a string, but being pushed apart by a spring between the two carts. The spring between them has a spring constant of 150 N/m and is compressed 4.0 cm. At t=0, the string is snipped. What are the final velocities of both carts? Don’t...
Imagine two carts with different masses colliding (m1 = 1.0 kg, m2 = 2.0 kg). If cart one is initially moving at 10 m/s and the other cart is stationary, calculate the final speed of each mass after they have a 100% elastic collision. Please show all work!
3) Two 1.0 kg masses are 1.0 m apart (center to center) on a frictionless table. Each has a +10uC of charge. a) What is the magnitude of the electric force on one of the masses? b) What is the initial acceleration of one of the masses if it is release<d and allowed to move?
Two 2.0 kg masses are 2.0 m apart on a frictionless table. Each has 1.0 μC of charge. What is the magnitude of the electric force on one of the masses? What is the initial acceleration of each mass if they are released and allowed to move?
Cart A (mass 2.0 kg) and Cart B (mass 3.0 kg) are separated by a compressed spring and attached to each other by a string. Initially they are sitting at rest on a frictionless surface. When the string is burned, Cart A moves to the left at 1.5 m/s. Cart B moves to the right and encounters a rough surface. Cart B comes to a stop after traveling a distance of 0.35 m on the rough surface. What is the...
Suppose that two carts, with a compressed spring between them (but not attached to either cart), are free to roll on a level table. The carts have very different masses and are initially stationary. Consider frictional losses to be negligible. The spring is released and the carts move apart. Are the final kinetic energies of the two carts equal, or is one greater than the other (if so, specify which is greater)? Explain your reasoning using fundamental physics principles, laws,...
4) A spring is compressed stored 1000 j of potential energy in it.Two identical masses of 1 kg each are on either of side the spring.What is the velocity of the two balls after the spring is released? 5) A 2Kg mass is pushed with 10N of force and has 1N of friction opposing its motion.If it starts from rest how fast is it moving after 2s? 6)A wheel on a robot has a radius of0.2m and is rotating at...
Two blocks on a frictionless table are held at rest with a compressed spring between them. When the blocks are released, the spring pushes them apart and they move in opposite directions. The spring has a spring constant of 215N / m and was compressed by 0.20 m. If one of the blocks moves at 1.50 m/s and the other moves away at 3.00 m/s , what is the mass of the heavier block in kg? (Hint: mechanical energy in...
1. A 30 cm spring with constant 70 N/m is compressed to 10 cm and placed between two carts. Cart A has mass m Skg and mg is unknown. Initially the system is at rest. After it is released it is observed that cart A has three times the velocity of cart B. a) What force must be exerted initially to keep the spring compressed? b) What is the work done to compress the spring? c) By considering conservation of...
