Answer:
The magnitude of displacement is 591km
Explanation:
Displacement is the change in an object's position from the origin. Displacement is a vector quantity, and thus has both magnitude and direction.
D = Xf - Xi = ∆X
Where D is displacement
Xf = final position
Xi = initial position
∆X = Change in position
The cars initial position Xi = 0
The cars finial velocity is (Distance traveled West - Distance traveled North)
Therefore D = (1250 W - 659 N) - 0
D = 591km N
(a) The acceleration of the two block is determined as 0.93 m/s².
(b) The tension in the string is 5.78 N.
<h3>Net force on the aluminum block</h3>
The net force on the aluminum block is calculated as follows;
<h3>Net force on the copper block</h3>
The net force on the copper block is calculated as follows;
where;
- T is tension in the string
- ma is mass of aluminum
- mc is mass of copper
- g is acceleration due to gravity
Solve for T using (1) and (2)
<h3>Tension in the string</h3>
From equation (1);
T = μm_ag + m_aa
T = 0.2(2)(9.8) + 2(0.93)
T = 5.78 N

Since this is definitely a RIGHT triangle (the little square in the corner),
the hypotenuse is 15, 'h' is the side opposite the 38-degree angle, and
sin(38°) = h / 15
Multiply each side by 15: h = 15 sin(38°)
= 15 (0.616)
h = 9.235
When practicing an oral presentation, you can prepare by writing a draft and practice reading aloud what you are going to say before your oral presentation.
Answer: Gravity will be on you since you are falling. For instance if you where skydiving you are free falling which will be similar to the car. Therefore gravity does play a role because whatever goes up must come down.
