Answer: 13.6 m/s
Explanation:
Since we are told the water balloon is in free fall and the air resistance is neglected, we are dealing with constant acceleration (due gravity) . Hence, we can use the following formula to find the velocity of this balloon at a given time and then its speed:
(1)
Where:
is the water balloon's initial velocity
is the acceleration due gravity (always directed downwards)
is the time
Rewritting (1) with the known values:
(2)
[tex]V=-13.6 m/s/tex] (3) This is the velocity of the balloon and the negative sign indicates is directed downwards
However, we were asked to find the speed, which is the magnitude of the velocity vector and is always positive.
Therefore, the speed of the balloon is 13.6 m/s
1. Outer planets - c. gaseous, spherical, cleared its neighborhood.
2. Density - f. amount of matter in an object, in a given space.
3. Orbital distance - e. Distance between any planet and the sun.
4. Mass - a. Amount of matter in an object.
5. Asteroid - b. Irregular rock orbiting between mars and Jupiter.
6. Volume - d. amount of space an object takes up.
The situation when nuclear fission occurs, some mass is lost is also called the mass defect and as a result the matter turns into energy. If you want to know where the mass does go Albert Einstein will be your helping hand : E = mc^2. Using this formulae you will solve the task and find out the direction of mass.
