Bob gained (80lbs x 14ft) = 1120 ft-lbs of energy.
Fred gained (110lbs x 14ft) = 1540 ft-lbs of energy
Since they both took the same amount of time, Fred's power (rate
of doing work) was greater than Bob's power (rate of doing work).
The kinetic energy of a moving object is equal to the
work necessary to bring it to its speed from rest
If an object is moving, then it is able of doing work. It
has energy of motion, or also known as kinetic energy (KE). The kinetic energy
of a thing hinge on the heaviness of the object along with its speed.
Answer:
18375g
Explanation:
Let's find the volume of the rectangular block.
Volume
= length ×breadth ×height
= 3.5 ×6 ×2.5
= 52.5cm³
Mass of the block
= 350(52.5)
= 18375g
