12th grade physics ap question. A baseball with a mass of 120 g is hit 21.8 m into the air. The ball is caught by the third baseman 2.5 m above the ground. What potential energy did the ball develop at its highest point? How much potential energy did it s...

For A you need to find the resultant. So since you know it moves 2.4 m/s north and 2.3 m/s east you can use the Pythagorean theorem to find it. For B i am not as sure about but it most likely is asking you to find the angle (based from east) where the boa...

Well lets break this up first. Clue 1: is i am a 3 digit number less than 200, only number possible there is 1. Clue 2: is the tens is 2x ones' place. so look at clue 3. clue 3: The ones place is 2. So then the tens is 2 times 2 which is 4. So the number...

yellow, blue, and red.

Well you know the force and mass. So use this formula: F=ma. F=250N m=20kg Just rearrange it and you will be able to get the maximum acceleration the sack can withstand before breaking.

okay that makes sense thanks.

Well first you add up the currently known grades: 84, 65, and 76. (known grades) Next multiply 80 by 4 to get the total amount for his test scores. (wanted average) Finally subtract the total for his known grades from his wanted average.

protons and neutrons. The electrons are on the outside keeping the protons inside.

well you can always just plug the answers into both equations and solve them. Answer: A

2x+6 < 5(x-3) distribute 5 into x-3 2x+6 < 5x-15 move all x to one side 6 < 5x-15-2x simplify 6 < 3x-15 move 15 to other side 6+15 < 3x simplify 21 < 3x get x alone by dividing 3 on both sides 21/3 < 3x/3 simplify 7 < x and that's how you solve it.

The answer is now!
