<h3>Answers:</h3>
- displacement = 3 km
- displacement = 0 km
=====================================================
Explanation:
Problem 1
Focus on the y axis which is the distance axis.
Point B has a y coordinate of 2
Point E has a y coordinate of 5
The displacement is 5-2 = 3, which means the person has moved 3 km.
--------------------------
Problem 2
Both D and E have the same y coordinate. So the displacement is 0 (since 5-5 = 0). No change in distance has occurred. During segment DE, the person is resting. By the way it is impossible to go back to D since it's impossible to go back in time.
Answer:
5 N
Explanation:
From the question,
The magnitude of the force that would be required to just loosen the nut when the force is applied perpendicularly at the end of the handle is
Fy = Fsinθ................. Equation 1
Where Fy = force acting perpendicular at the end of the handle, F = Force applied to the handle, θ = angle of inclination of the force to the end of the handle.
Given: F = 10 N, θ = 30°
Substitute these values into equation 1
Fy = 10(sn30°)
Fy = 10(0.5)
Fy = 5 N.
Answer: I hope this helps you
Explanation:
Answer: 2.19 seconds
Explanation:
<u>Given:</u>
Initial speed, u = 0 m/s
Acceleration of the boat, a = 5 m/s^2
Distance between the boat and dock, d = 12 m
Using the third kinematics equation to solve for time:
d = u*t + (1/2)*a*t^2
12 = 0*t + (1/2)*5*t^2
t = sqrt (12*2/5)
t = 2.19 seconds
Therefore, it will take the boat approximately 2.19 seconds to reach the dock
When the two forces are acting in the opposite direction, then the resultant of the two vectors will be at a minimum. The value of the force will be either 2 Newton or -2 newton.
<span>. It is the simplest
way to prove and explain the situation under which the resultant of the two
vectors will be at a minimum. The situation under which the resultant of the
two vectors will be maximum is when the two forces of 5N and 7n will act in the
same direction and create a combines force of 12N.</span>
