Question

an object moves 1st one third of the distance with 40m/s next one third with 30m/s and remaining distance with 20m/s .object returns to the starting point with 80m/s. find average speed and average velocity​

Answer 1

Answer:

Kinetic energy is the energy an object has because of its motion.

If we want to accelerate an object, then we must apply a force. Applying a force requires us to do work. After work has been done, energy has been transferred to the object, and the object will be moving with a new constant speed. The energy transferred is known as kinetic energy, and it depends on the mass and speed achieved.
