A 65.8-kg person throws a 0.0413 kg snowball forward with a ground speed of 32.5 m/s. A second person, with a mass of 58.7 kg, catches the snowball. Both people are on skates. The first person is initially moving forward with a speed of 2.51 m/s, and the second person is initially at rest. (Disregard the friction between the skates and the ice.)
What are the velocities of the two people after the snowball is exchanged?

Explanation:

The statement is described physically by means of the Principle of Momentum Conservation. Let assume that first person moves in the positive direction:

First Person

Second Person

The final velocities of the two people after the snowball is exchanged is:

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.

6 cos 34, 6 sin 34 trig
