A chain lying on the ground is 10 m long and its mass is 70 kg. How much work (in J) is required to raise one end of the chain t

o a height of 6 m
Physics
1 answer:
Vikki [24]3 years ago
7 0

Answer:

The work done in moving the chain is 4116 J

Explanation:

Given;

mass of the chain, m = 70 kg

length of the chain, l = 10 m

vertical height through which one end of the chain was raised, h = 6 m

Work done in raising this chain to this height is equal to potential energy due to this vertical height

W = PE

W = mgh

where;

m is mass of the chain

g is acceleration due to gravity

h is the vertical height through which the chain was raised

W = 70 x 9.8 x 6

W = 4116 J

Therefore, the work done in moving the chain is 4116 J

A baseball is thrown by the center fielder (from shoulder level) to home plate where it is caught (on the fly at eye level) by t
marishachu [46]

At the highest point of the trajectory the vertical component will have its zero velocity, and the descent caused by the force of gravity will begin.

Since the ball is thrown with a certain speed, the vertical component reaches its highest point (upwards), until returning to the receiver who will receive the ball with the same vertical component but in the opposite direction (downwards).

Therefore the vertical component will have its highest value at launch.
