In an experiment, the 1 kg cart collides with a 3 kg cart but doesn’t stick to it. Instead, the 3 kg cart gets knock forward by the 1 kg cart at 0.30m/s, which comes to rest after the collision.
If the positive direction is to the right, what was the initial velocity of the 1.0-kg cart?

Explanation:

Given that,

Mass of the cart,

Mass of the cart 2,            

Final speed of cart 2,

Final speed of cart 1 is 0 as it comes to rest.

Let us assume that the initial velocity of the cart 2 is 0. So using the conservation of linear momentum as :

So, the initial velocity of the 1.0-kg cart is 0.9 m/s.

step-by-step explanation: a third of 24 is 8, 8 times 3 is 24 so 8 - 2 would be 6

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.
