An effective early childhood curriculum can be learning how to read and write. Without learning how to read, we wouldn’t be able to communicate through this app, or through online school. We wouldn’t know directions, and we wouldn’t be able to enjoy stories. If we didn’t know how to write, I would not be able to help you figure out the answer to this problem, and your teacher wouldn’t be able to grade anything. Think about it, you ir entire education is based of being able to read and write.
Hope this helps :)
Answer: it depends on the mass of the pendulum or on the size of the arc through which it swings.
Explanation:
Explanation:
We have,
Mass of a particle is 0.6 kg
Speed at A is 2 m/s
Kinetic energy at B is 7.5 J
(a) The kinetic energy at A is given by :

(b) Kinetic energy at B is given by

(c) The work done on the particle as it moves form A to B is given by work energy theorem as :

It's zero when you drop it and 18.1 m/s downward when it hits the ground.
