A train starts from rest .It moves through 1km in 100s with uniform accelaration . What will be its speed at the end pf 100 s

Explanation:

Distance = 1 km

= 1000m

Time = 100 sec

Speed = distance / time

= 1000 / 100

= 10 m/s

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
