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
Answer:
The acceleration is 3.16x10¹⁷ m/s².
Explanation:
First, we need to find the magnitude of the Coulombs force (F):

<u>Where</u>:
K is the Coulomb constant = 9x10⁹ Nm²/C²
q₁ is the charge = 20x10⁻⁹ C
q₂ is the electron's charge = -1.6x10⁻¹⁹ C
d is the distance = 1.0 cm = 1.0x10⁻² m
Now, we can find the acceleration:

Therefore, the acceleration is 3.16x10¹⁷ m/s².

Answer:
a. 25m
b. 25m
c. 35m
Explanation:
Given the distances walked as 15m east and 20m north:
Using Pythagoras Theorem, we calculate displacement as:

Hence, the resultant displacement is 25m
b. The distance from her start point is obtained by drawing a straight line from her final point to her initial point.
Given the distances walked as 15m east and 20m north:
Using Pythagoras Theorem, we calculate displacement as:

Hence, she is 25m away from her starting point.
c. The distance traveled is calculated by summing the total distance walked:

Hence, the total distance traveled is 35m
