Elements are arranged from left to right and top to bottom in order of increasing atomic number. Order generally coincides with increasing atomic mass.
Answer:
False
Explanation:
Potential energy is stored energy, so it is not in motion. Kinetic energy is the energy in motion.
The initial speed of the sled at the given height is 4.85 m/s.
<h3>Initial speed of the sled</h3>
Apply the principle of conservation of energy;
K.E = P.E
¹/₂mv² = mgh
v² = 2gh
v = √2gh
where;
- h is the vertical height reached
- g is acceleration due to gravity
v = √(2 x 9.8 x 1.2)
v = 4.85 m/s
Thus, the initial speed of the sled at the given height is 4.85 m/s.
