The displacement of the object that moved 4 meters north, then 3 meters east is 5 meters.
<h3>
What is displacement?</h3>
Displacement is change in the position of an object. It can be described as the shortest distance between the initial and final position of an object.
The displacement of the object is calculated as follows;
d² = 4² + 3²
d² = 25
d = 5 m
Thus, the displacement of the object that moved 4 meters north, then 3 meters east is 5 meters.

To the right, if you push something left the friction is to the right
13.0÷1.69
= seconds for the cyclist to completely stop
first solve -1.3 to the second power or -1.3 squared by multiplying -1.3 by itself
((-1.3)×(-1.3 )=1.69)
then divide 13 by 1.69
we are dividing because we are solving a deceleration equation and by multiplying 2 negatives the sum will always equal a positive and if we multiplied 13 by 1.69 we would turn this into an accelleration equation.
so divide 13 by 1.69
(13÷1.69=7.6923076923)
Answer:
a ) 270 N
b )413.65 N
Explanation:
weight of the refrigerator = reaction force ( R )
= mg
= 63 x 9.8
R = 617.4 N
Maximum friction possible
= coefficient of friction x R
= .67 X 617.4
= 413.65 N
When force 270 N is applied , due to friction, the body does not move .
The friction force adjusts itself to the external applied force to prevent the body to budge.
Hence the friction force acting in this situation = 270 N
b ) The maximum friction possible is 413.65 . If we apply a force equal to or exceeding 413.65 N , body will move. Hence 413.65 N is the answer.
