A2.0-kg cart collides with a 1.0-kg cart that is initially at rest on a low-friction track. after the collision, the 1.0-kg cart moves to the right at 0.50 m/s and the 2.0-kg cart moves to the right at 0.25 m/s . if the positive direction is to the right, what was the initial velocity of the 2.0-kg cart?

Initial velocity of first cart will be 0.5 m /sec

Explanation:

We have given mass of the cart

Its collides with other cart of mass

Let the initial velocity of cart 1 is

As the car 2 is initially at rest so = 0 m/sec

After the collision velocity of first cart is 0.25 m/sec

So = 0.25 m/sec and velocity of second cart is 0.50 m /sec

So = 0.5 m/sec

From conservation of momentum we know that

= 0.5 m /sec

So initial velocity of first cart will be 0.5 m /sec

the closer the planet is to the sun, the larger the gravity

friction

explanation:

they us to move forward and backwards
