4. an object (object a) with a mass of 500 kg is traveling in a straight line from west to east at a constant velocity of 34 m/s. object a encounters a headwind blowing with a force of 25 n for six minutes and then proceeds to collide with a stationary object (object b) with a mass of 300 kg, thereby reducing the velocity of object a to 4 m/s. what is the final velocity of object b?

Physics: acceleration questions 1) an egg is thrown vertically downward from a window. if the egg was released with a velocity of 10.0m/s and it strikes the ground at a velocity of 25.0 m/s, how long did it take the egg to reach the ground ? 2) an object is dropped from the roof of a building. if the object takes 2.5s to reach the ground, what was the velocity of the object when it reached ground? you so much. : p and for this question an object accelerates uniformly at a rate of 1.50m/s^2 [e] for 10.0s. if the velocity of the object reaches 25.0m/s [e] at this time, what was the initial velocity? apparently the answer for that is 10.0m/s [e], but i keep getting -10.0 you so much to anyone who could !
