Answer:
About 2.19 seconds
Explanation:

Since the ball is dropped from rest, there is no initial velocity, and you can write the following equation:

Hope this helps!
Answer:
The kinetic energy of the baseball is 107.83 J
Explanation:
Given;
mass of the baseball, m = 144 g = 0.144 kg
velocity of the baseball, v = 38.7 m/s
The kinetic energy of the baseball is given by;
K.E = ¹/₂mv²
where;
m is mass of the object
v is speed of the object
K.E = ¹/₂(0.144)(38.7)²
K.E = 107.83 J
Therefore, the kinetic energy of the baseball is 107.83 J
Answer:
hmm sorry but ill answer it later
Explanation:
The amount of energy transferred to an appliance is depends on its power and length of time it is switched on. The wires attached to the appliance conduct the electricity and send it to the main motor function.
