Answer:
25J
Explanation:
Given parameters:
Mass of the watermelon = 2kg
Speed before touching the ground = 5m/s
Unknown:
Kinetic energy = ?
Solution:
To solve this problem, we must understand that kinetic energy is the energy possessed by a body in motion.
K.E = m v²
m is the mass
v is the velocity
Now, insert the parameters and solve;
K.E = x 2 x 5² = 25J
Answer:
40.53 kg
Explanation:
Juggles 's mass = Mj
Bangles 's mass = 70 kg
Potential Energy is the Energy that an object gets due to its height of location
<em>Potential Energy = mass * gravitational acceleration * height</em>
Juggeles' s Potential Energy = Bangles potential energy
Mj * g * 3.8 = 70 * g * 2.2
Mj = 40.53 kg
Answer:
You can describe the motion of an object by its position, speed, direction, and acceleration. An object is moving if its position relative to a fixed point is changing. Even things that appear to be at rest move.
Explanation:
Either convection or thermal energy
A transverse wave always move perpendicularly from its medium. In the problem the medium is the rope. So when the transverse wave movement is left and right, the perpendicular equivalent movement of the rope is up and down.
