Suppose a clay model of a koala bear has a mass of 0.205 kg and slides on ice at a speed of 0.720 m/s. it runs into another clay model, which is initially motionless and has a mass of 0.320 kg. both being soft clay, they naturally stick together. what is their final velocity (in m/s)? (enter the magnitude.)

Final velocity, v = 0.28 m/s

Explanation:

Given that,

Mass of the model,

Speed of the model,

Mass of another model,

Initial speed of another model,

To find,

Final velocity

Solution,

Let V is the final velocity. As both being soft clay, they naturally stick together. It is a case of inelastic collision. Using the conservation of linear momentum to find it as :

V = 0.28 m/s

So, their final velocity is 0.28 m/s. Hence, this is the required solution.

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.
