Answer:
Fx = -7042.86N (Taking the right as positive sense of motion)
Fy = 2154.29N.
Explanation:
The full solution can be found in the attachment below. The approach to the solution involves the summation of the respective components of the momentum along the horizontal and vertical axis.
To the right is taken as positive sense of motion and the left as negative sense of motion.
The basic statement of Newtown's second law have been used which is
M(v2 – v1) = Ft
See the attachment below for the complete calculation procedure.
According to the law of reflection, when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection.
So in the above situation, if the incident ray makes an angle of 65° with respect to the normal to the mirror's surface, the angle of reflected ray will also be equal to 65 degrees. The attached image will explain this better.
So the answer is,
c. 65 degrees

Answer:
The cart moved away from the starting point between 8 s and 10 s.
Explanation:
Given that :
Which of these does NOT describe the cart’s motion on this graph?
The cart was at rest between 5 s and 7 s : From the distance of golf cart Vs time graph ; the car was at rest between 5s and 7s as the graph was flat with that time interval, meaning there was no change in distance.
The cart moved toward the starting point between 7 s and 12 s. : The graph depicts a negative slope at this time interval as the distance from starting point fell from about 26 m to 10 m
The cart moved away from the starting point between 8 s and 10 s. : At this time interval, the cart moved towards the starting not and not away. This could be seen in the decrease in Distance from starting point between the tune interval.
The cart moved away from the starting point between 2 s and 5 s. - - > The cart moved away from the starting point, with the positive slope signifying an increase in distance.
Therefore, The cart moved away from the starting point between 8 s and 10 s does not describe the motion of the cart on the graph.
