Answer:
25 m/s
Explanation:
This question can be solved using equation of motion
where
v is the final velocity
u is the initial velocity
s is the distance covered while moving from initial to final velocity
a is the acceleration

Given
box moved for distance of 62.5 m
Friction slows the box at –5.0 m/s2----> this statement means that there is deceleration , speed of truck decreases by 5 m/s in every second until the box comes to rest. Friction causes this deceleration.
thus in this problem
a = -5.0 m/s2
V = 0 as body came to rest due to friction deceleration
u the initial velocity we have to find
the initial velocity of box will be the same as speed of truck, as the box was in the truck and hence box will pick the speed of truck.
so if we find speed of box, we will be able get sped of truck as well.
using equation of motion
Thus, initial speed with the truck was travelling was 25 m/s.
Acceleration is constant in free fall. So it would again be 9.8 m/s².
Answer:
Inverse multiplexer or demultiplexer
Explanation:
An inverse multiplexer or demultiplexer behaves in an opposite way to the multiplexer. It collects data from a single source and breaks it down into several smaller outputs.
<em>A transponder performs the function of transmitting and receiving data in digital communication.</em>
<em>A multiplexer collects data from several analog or digital input signals and forwards them to a single output line</em>
<em>codec is used to decode and decode digital data streams</em>
<em>intelligent terminals are simply terminals that have processing power just like a smart keyboard.</em>
Sedimentary rock is formed because it absorbs deposits from the Earth surface and they eventually form a hard clay-like structure.
- Mass=m=44.9kg
- Distance=s=20.5m
- initial velocity=u=0m/s
- Final velocity=v=62m/s
- Force=F
- Acceleration=a
