A toy car with a mass m is accelerated in a hallway with a force that varies uniformly from 0 Newtons to three times the weight of the car over a timet. At that point, the engine shuts down, and the car continues to travel at a constant
speed along the hallway for a time equal to t
This hall can be considered to be frictionless from the start of the trip to this position. After time 2t has passed, the
car reaches a rough surface with a force of friction equal to 0.5 mg and continues along this surface until timet
when the car comes to rest.
a. Create a graph of Force vs. Time for the entire trip of the car.
b. Calculate the impulse given the car by the engine during the time when the force acts, t.
c. Calculate the momentum lost by the car during the time when the force of friction is acting.
d. Calculate the total time until the car stops

step-by-step explanation:

if you meant, "on the way from (3, 2) to (3, 14):

x does not change; y increases by 12.

ensure that you have copied down this problem correctly.   .

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
