Answer:
Force is a vector quantity which when applied to an object can cause change in its velocity. When Force is applied to an object, the object if stationary moves to a certain distance depending upon the amount of force applied.
A pulley is a wheel with a groove that holds a rope, cable or belt, and is used to help lift an object.
The relationship of Force and Distance is the same for a fixed pulley as well. Except for one thing:
Normally the distance covered by an object is in the direction of the Force.
Using a pulley, an object can be moved with that same Force in a different direction. Using a pulley, a person can apply force in a direction suitable for him while moving the object.
<em> Force = mass of an object * Distance Covered</em>
Many different problem such as racial slurring and racial profiling
It will take 21s for yhe alligator to crawl that distance. Reported answer contains 2 Significant Figures.
Answer:
The frictional force producing this deceleration would have a magnitude of
.
Explanation:
The velocity of this object changed by
in
. The acceleration of this object would be:
.
Let
denote the mass of this object. By Newton's Second Law of Motion, the net force on this object would be:
.
(
.)
If the floor is level, friction would be the only unbalanced force on this object. Thus, the magnitude of the frictional force on this object would also be
, same as the magnitude of the net force on this object.
Distance = 2000m
Time = 35 minutes = 35×60 sec = 2100 sec
We know, Speed = Distance/Time
Therefore, Speed
= 2000m/2100s = 20/21 m/s
Answer: 20/21 m/s
