uppose the underlying speed of the plane is 100km/h 100km/h in the upward heading (in the 2-D plane of this advanced screen).

After the plane finishes a large portion of a circle, it will point downwards. However, it will in any case have a similar speed of 100km/h100km/h. You can likewise call this −100km/h−100km/h in the upward course.

In this way, the adjustment in speed is equivalent to the underlying speed subtracted from the last speed.

Change in speed = −100km/h−100km/h−100km/h−100km/h in the upward heading.

Change in speed = −200km/h−200km/h in the upward heading.

Three identical balls are placed on a frictionless horizontal surface touching each other. They stick to each other because of adhesive. Another ball of same radius and mass m is placed over the void created by the three balls. Find the forces applied by the balls kept on the floor to each other if the system remains in equilibrium.
