Question
If you could provied an explaination I would be thankful.
A car travels a certain distance along a straight road (in the +x direction). The distance the car travels as When the car changes speed it does so uniformly. Selected the appropriate choice for each statement: T-true, F-Flase, G-Greater than, L -Less than, E-Equal to (If the first is T, the second is G, and the rest E, enter TGEEE) The x-acceleration is...zero at 38 sec The acceleration magnitude at 15 sec is.the acceleration magnitude at 38 sec. The speed at 52 sec is the speed at 73 sec. The x-acceleration is zero at 23 sec The speed is zero at 23 sec. At 52 sec, the speed is as high as it gets. Using the graph above, calculate the average speed of the car for the period from 0 to 60.0 s.Explanation / Answer
1. GLGEET
explaination :- A) slope of x-t graph represents velocity and slope of v-t graph represents acceleration. so t= 38 sec slope is x-t graph is positive then accleration is positive constant.
B) t= 15 sec a = 0 m/s2 and t= 38s a= some positive constant
C) t=52 sec slope is grater than to at t=73s
D) velocity is zero at t= 23s then accleration is equal to zero.
E) slop of x-t graph at t= 23s is equal to zero then v= 0m/s
F) slope is positve at t= 52s.
2. average speed = distance / time = 960/60 = 16 m/s
