You are training to run the 100 m race at a track and field meet. You time yourself and find you can run it in 10 seconds. How fast are you abke to run it

Explanation:

= Displacement =

= Time taken =

Velocity is given by

The person is able to run at a speed of in order to complete the race in the given time.

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
