Explanation:
Mass of ball A, 
Mass of ball B, 
Initial velocity of ball A, 
Initial velocity of ball B, 
We need to find the final velocity of each ball. For a perfectly elastic collision, the coefficient of restitution is equal to 1. It is given by :
are final velocities of ball A and B
...........(1)
Using the conservation of linear momentum as :
..............(2)
On solving equation (1) and (2) using calculator we get :
So, the final velocities of ball A and B are 4.2 m/s and 17.2 m/s. Hence, this is the required solution.
Answer: 4800 N/m
Explanation:
Given
mass of rock 
Height of cliff 
compression in the spring 
Here, potential energy is converted into kinetic energy which in turn converts to elastic potential energy of the spring
Answer:
Explanation:
Hold time is referred as the minimum time after active edge of clock after which data must be stable so hold violation will cause the incorrect data to be added.
In such circuit the first thing that can be done to fix this will be :
- Reset the clock to the start/endpoint to make end point clock arrive earlier.
- Insert a buffer chain to increase the propagation time.
- Add delays
Explanation:
1 mile = 1609m
Distance=260 miles= 418340 m
Speed= 40 m/s
Time = distance/speed
= 418340/40
=10458.5 seconds
= 2.9 hours
