A ball of mass o.8 kg is thrown against a wall. The ball strike the wall horizontally with a speed of 11 m/s, and it bounces back with the same speed. The ball is in contact with the wall for 0.05s. What is the average force exerted on the wall by the ball?
To find the average friction force when a person has a usual 1 km walk, we can follow these steps:Step 1: Understand the Motion When a person walks, they start from rest and eventually come to a stop. This means that the initia
. What is the average braking force. Average force during braking:The average force applied by the brake is the multiplication of the car's mass with the deceleration of the car. Now the deceleration of the car is =vi−vft. Therefore, average force by the b...

The average organization has976 individual applicationsholding its data, and it’s hard to ensure that everyone has the most up-to-date information across all these systems. Integration solves this by connecting all of the applications across the enterprise so people can access the exact data they...
need flexibility. As our world of work continues to transform faster and is often disrupted, a contingent workforce gives companies the ability to scale staff up or down in various business areas as needed. This allows organizations to account for the volatility in their industry and the job ...
