Question

The diagram shows a compressed spring between two carts initially at rest on a horizontal frictionless surface. Cart A has a mass of 2 kg and cart 15 has a mass of 1 kg. A string holds the carts together. What occurs when the string is cut and the carts move apart? 1. The length of time that the force acts on cart A is twice the length of time the force acts on cart B 2. The magnitude of the force exerted on cart A is one-half the magnitude of the force exerted on cart B 3. The magnitude of acceleration of cart A is the same as the magnitude of the acceleration of cart B 4. The magnitude of the acceleration of cart A is one-half the magnitude of the acceleration of cart B 5. The magnitude of the impulse applied to cart A is twice the magnitude of the impulse applied to cart B

Explanation / Answer

Here ,

for the both carts , as spring will exert equal force on both the cars

and the time period of application of force will be equal irrespective of mass of each cart.

the correct options are :

4.the magnitude of the acceleration of cart A is one half the magnitude of acceleration of cart B
