<h2>
Displacement along west = 3612 m</h2><h2>
Displacement along north = 4633.50 m</h2>
Explanation:
Let east be positive x axis and north be positive y axis
Velocity of boat = 2.8 m/s in a direction 52° north of west.
Velocity, v = -2.8 cos 52 i + 2.8 sin 52 j = -1.72 i + 2.21 j m/s
Time taken = 35 min = 35 x 60 = 2100 s
Displacement = Velocity x Time
Displacement = (-1.72 i + 2.21 j) x 2100
Displacement = -3612 i + 4633.50 j m
Displacement along west = 3612 m
Displacement along north = 4633.50 m
Answer:
Explanation:
Let's analyze the situation presented in order to know which answer is correct.
When the stick collides with the puck, it exerts a force for a certain time and discants. / After this time the horizontal force decreases to zero and the disk continues to move by the action of the initial velocity on the x axis and the acceleration of gravity on the y axis.
Therefore, after the collision, the only force that acts on the disk is the gravitational attractive force (WEIGHT), directed on the axis and in a negative direction.
The correct answer is:
C) Since there is no frictional force exerted on the puck, a normal force is not exerted on the puck, but the gravitational force is exerted on the puck
Neon light recharge them self with more light and electricity, they rapidly give out
the energy they absorbed to get themselves back to normal again. They
do this by giving out tiny packets of light energy
called photons. I;m not sure if this helps but you gave no info really on what you were asking like if there were choices that would have been helpful to see :p
Answer:
The final velocity of the plane is 100 m/s.
Explanation:
To solve this problem, we will use one the kinematics equations. First, let's write out what information we have given and what we are trying to find.
x = 5.0 * 10^2 m
a = 5.0 m/s^2
v1 = 0 m/s (starts from rest)
v2 = ? (we are trying to find the final velocity)
Using the variables listed above, we can select the following equation to use:
v2^2 = v1^2 + 2ax
Now, we should plug in our known values and isolate the unknown variable.
v2^2 = 0 + 2(10)(500)
To solve for the velocity, we should take the square root of both sides of the equation to get rid of the square on the left side of the equation.
v = sqrt(10,000)
Now, we must simplify the right side of the equation to solve for v (the unknown variable).
v = 100 m/s
Therefore, your answer is 100 m/s.
Hope this helps!
